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.
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.
What's the difference between instantaneous velocity and instantaneous acceleration?
Instantaneous velocity is the rate at which an object is moving in a uniform direction, distance per unit time, at any given instant in time. instantaneous acceleration is the rate at which an object's velocity is changing at any given instant in time
Is average acceleration equal to instantaneous acceleration for a uniformly accelerated car?
Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion. Example : A car accelerating at 1m/s2 uniformly in a straight line.
If the instantaneous velocity of an object is constant then so is acceleration.?
the velocity increases at a constant rate
What is a instantaneous velocity?
Instantaneous velocity: The velocity of an object at one moment in time.
Can the average speed ever equal the instantaneous speed?
When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.
What is an object doing at the moment it's instantaneous acceleration is zero?
it can be moving at constant velocity or staying still
When is an object's average velocity equal to its instantaneous velocity?
If the velocity is constant (i.e., there is no acceleration). Terminal velocity is an example, although any constant velocity would fit this description.
Define speed at which an object is moving at a given instant time?
If the displacement of the object (its position) can be described as a functional or algebric equation, you can find the instant speed of this object by calculating the derivative of its displacement equation, knowing that speed is the first derivative of position and acceleration, its second.
What is acceleration at instantaneous maximum velocity?
In the case of an object thrown, batted, teed off, or dropped, its acceleration at the instant of its maximum velocity is 9.8 meters per second2 downward.
What formula do you use to calculate the acceleration of an object moving in a straight line?
Acceleration = Final velocity - Initial velocity / time
What is the difference between object moves wint uniform acceleration and object moves with no acceleration?
An object moving with uniform acceleration has a uniform change in velocity over time, and its velocity-time graph will be a straight line with either a positive or negative slope. An object moving with no acceleration has constant velocity, and its velocity-time graph will be a straight, horizontal line with zero slope. Refer to the related link for illustrations.
