What else can I help you with?
What formula do you use to calculate the acceleration of an object moving in a straight line?
Acceleration = Final velocity - Initial velocity / time
What does velocity divided by the time interval equal?
It equals an undefined entity. The average acceleration of an object equals the CHANGE in velocity divided by the time interval. The term "change in velocity" is not the same as the term "velocity", "average velocity", or "instantaneous velocity".
What is the acceleration of a car that travels in a straight line at a constant speed of 110 km h?
The acceleration of an object that travels in a constant straight line velocity is zero.
How is an object moving if a slanted straight line on a speed versus time graph represents its motion?
A straight slanted slope on a velocity-time graph indicates that the object is moving with a constant acceleration.
When an object moves with inconstant velocity does its average velocity differ from its instantaneous velocity?
Generally it is a Yes. Instantaneous velocity is the exact velocity at a particular time in the course of the movement. However, average velocity is the average of all the instantaneous velocity over a period of time. It is also known as speed in everyday life. As a result, the movement of an object over a time period under varying velocity denotes a varying instantaneous velocity which could be different from the average velocity. It is however, possible that the instantaneous velocity equates to the average velocity at a certain point over the duration of movement. For example, a ball is traveling at instantaneous velocity of 99m/s at t=1s , 100m/s at t=2s and 101m/s at t=3s. the average velocity over the 3s period is hence 100m/s which coincides with the instantaneous speed at t=2s.
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 will be instantaneous acceleration if average acceleration is zero?
If the average acceleration is zero, it means that the object's velocity is not changing over time. Since instantaneous acceleration is the acceleration at a specific moment in time, it can still have a non-zero value depending on the instantaneous velocity of the object at that moment.
What is instentaneous acceleration?
Instantaneous acceleration is the rate of change of velocity at a specific moment in time. It indicates how quickly the velocity of an object is changing at that instant. It is typically calculated as the derivative of velocity with respect to time.
Is the rate at which an object changes velocity?
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.
If the instantaneous velocity of an object is constant then so is acceleration.?
the velocity increases at a constant rate
What is acceleration at instantaneous maximum velocity?
The acceleration at instantaneous maximum velocity is zero, as the velocity is not changing at that moment.
When is an object's average velocity equal to its instantaneous velocity?
An object's average velocity is equal to its instantaneous velocity when the object is moving at a constant speed in a straight line. This means that the object covers equal distances in equal intervals of time, resulting in the average velocity over a period of time being equal to the instantaneous velocity at any given moment within that period.
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.
In physical science what are the 3 types of acceleration?
The three types of acceleration in physical science are constant acceleration, variable acceleration, and instantaneous acceleration. Constant acceleration is when an object changes its velocity at a steady rate, variable acceleration is when an object changes its velocity at different rates, and instantaneous acceleration is the acceleration of an object at a specific moment in time.
Is average acceleration equal to instantaneous acceleration for a uniformly accelerated car?
No, average acceleration is the overall change in velocity over a specific time interval, whereas instantaneous acceleration is the acceleration at a specific moment in time. For a uniformly accelerated car, the average acceleration is constant over the entire interval, but the instantaneous acceleration can vary at different points during that interval.
What does a tangent to a velocity-time graph measure?
A tangent to a velocity-time graph represents the instantaneous acceleration of an object at that specific moment in time. It shows how the velocity is changing at that particular point.
In which type of motion is the average velocity of an object equal to its instantaneous velocity?
The average velocity of an object is equal to its instantaneous velocity in uniform motion. Uniform motion occurs when an object moves at a constant speed in a straight line, resulting in a constant velocity throughout the motion.
