A particle moving with a constant velocity has no acceleration. Acceleration is the change in velocity over time. If the velocity is constant, there can be no acceleration. For you Calculus junkies, dv/dt (v is velocity) is acceleration, and will equal zero if v is a constant.
The acceleration of an object at any particular time is known as its instantaneous acceleration. If acceleration is a function of time -- that is, if a varies with time, t-- then the evaluation of a at a particular time, tp, is the instantaneous acceleration at t = tp. Let's say acceleration is given by the linear equation a(t) = 10t - 5. When t = 1, a = 5 because a(1) = 10 * 1 - 5 = 5. It is equal to exactly 5 only when t is exactly 1. The acceleration is something less than 5 when t < 1, and it is greater than 5 when t > 1. We say the instantaneous value of a is 5 at t = 1.
When a particle is moving in uniform circular motion , its speed is constant . Velocity of particle changes from point to point due to change of direction of particle in uniform circular motion. This change in velocity vector leads to an acceleration which acts towards the center of circular path. The acceleration is known as Centripetal acceleration.
Since the direction changes, the velocity changes - and therefore there is an acceleration.
The acceleration is towards the center - therefore the acceleration changes all the time (since its direction changes). The magnitude can be calculated by:a = v^2 / r
or:
a = omega^2 x r
Where "^" stands for power, v for velocity, r for radius, omega for angular velocity (in radians/second).
The acceleration of an object at a given time is the rate at which its velocity is changing at that specific moment in time. It is typically measured in units like meters per second squared (m/s^2).
Acceleration, in physics, is the rate of change of velocity of an object. It is also written as a = F/m, where F is the net force applied to a mass, m.
Acceleration in physics means that an object that is moving continues moving faster and faster. Typically cars accelerate from the starting point to a midpoint when traveling.

To find the acceleration of an object moving in a straight line you must calculate the charge in distance during unit of time?
To find the acceleration of an object moving in a straight line, you must calculate the change in velocity during a unit of time. Acceleration is the rate of change of velocity over time, not distance. It is given by the formula acceleration = (final velocity - initial velocity) / time.
What graph are used to analyze the motionof an accelerating objects?
A velocity-time graph is used to analyze the motion of an accelerating object. The slope of the graph represents the acceleration of the object - a steeper slope indicates a greater acceleration. The area under the curve represents the distance traveled by the object.
What is the importance of uniform acceleration graph in physics what is instantaneous velocity?
Uniform acceleration graphs help visualize how an object's velocity changes over time. They show a constant rate of change in velocity, which can be used to calculate properties like displacement and time. Instantaneous velocity is the velocity of an object at a specific moment in time, representing the object's speed and direction at a given instant.
What is and acceleration force divided by mass?
Acceleration force divided by mass gives you the acceleration of an object. This is a measure of how quickly the object's velocity is changing over time.
Can a stationary object have a non zero angular acceleration?
No, a stationary object cannot have a non zero angular acceleration. Angular acceleration is a measure of how an object's angular velocity changes over time, so if an object is not rotating, its angular acceleration is zero.
What is the formula used to find distance?
The distance travelled by an object in a given time is given by:Distance = Speed * TimeAlternatively for an object that is accelerating:Distance = (Speed of object before acceleration is applied * Time) + (0.5 * Acceleration * Time squared)If the object is accelerating from speed zero, the first set of brackets is irrelevant.Also, if the object is falling to the ground, acceleration = 9.81
Measurement of the change in the velocity of an object divided by the time it takes for this change to occur is?
Acceleration. It is a vector quantity that represents how quickly an object is changing its velocity. It is given by the formula: Acceleration = (Change in Velocity) / (Time taken).
What equation do you use for acceleration?
The equation for acceleration is given by the formula: acceleration = (final velocity - initial velocity) / time. This equation calculates the rate at which an object's velocity changes over time.
Who has larger acceleration?
An object with a greater acceleration covers a larger change in velocity in a given time period compared to an object with a smaller acceleration. It is determined by the rate of change of velocity, with higher acceleration leading to a faster increase in speed.
How can you calculate the acceleration of an object moving in a straight line by?
You can calculate the acceleration of an object by dividing the change in its velocity by the time taken for that change to occur. The formula for acceleration is acceleration = (final velocity - initial velocity) / time.
What's the difference between instantaneous velocity and instantaneous acceleration?
Instantaneous velocity represents the rate of change of an object's position at a specific moment in time, while instantaneous acceleration represents the rate of change of an object's velocity at a specific moment in time. In other words, velocity measures how fast an object is moving, while acceleration measures how fast the object's velocity is changing.
What is the acceleration of an object that has a force of N and the mass of kg?
The acceleration of an object is given by the formula a = F/m, where 'a' is acceleration, 'F' is force, and 'm' is mass. Therefore, the acceleration of the object is N/kg.
What is an increase of speed during a given interval of time?
Acceleration is an increase in speed during a given interval of time. It measures how quickly an object's velocity is changing. Acceleration can be positive (speeding up), negative (slowing down), or zero (constant speed).
How does acceleration affect distance?
Acceleration affects distance by influencing how quickly an object changes its speed. The higher the acceleration, the faster the object will cover a certain distance in a given amount of time. A higher acceleration will result in a shorter distance covered in a shorter time, whereas a lower acceleration will result in a longer distance covered over the same time period.
What does acceleration graph show?
An acceleration graph shows the rate at which the velocity of an object is changing over time. It can indicate whether an object is speeding up, slowing down, or maintaining a constant velocity. The slope of the graph at any given point represents the acceleration of the object at that point.
How do you get the acceleration of an object?
Acceleration= Distance divided by time
An object is one that is gaining speed?
An object that is gaining speed is undergoing acceleration, which means its velocity is increasing over time in a particular direction. This could be the result of a force acting on the object, like gravity or a push. The object's acceleration can be measured by how much its speed changes in a given amount of time.
