What is the increase of velocity over a period of time is?

Increase of velocity over a period of time is called acceleration.

What is a direction of change over a period of time?


What is it called when the rate at which velocity changes over time?

The rate of change of velocity over time is called acceleration. It can be as a result of increase or decreased speed, or change of vector.

What is a change in velocity in given period of time?

Change in velocity = Velocity at the end of the period minus velocity at the start of the period.

What is the physics definition for acceleration?

Acceleration is a change in velocity over a period of time.

What is the relationship between average velocity and instantaneous velocity?

The average velocity over an time interval is the average of the instantaneous velocities for all instants over that period. Conversely, as the time interval is reduced, the average velocity comes closer and closer to the instantaneous velocity.

You increase your walking speed from 1ms to 3ms in a period of 1s what is your acceleration?

Acceleration is the change in velocity of a body over time. This means that we can determine it quite simply by dividing the change in velocity by the change in time. In your case, we have a change of velocity of 2m/s, and a change in time of 1s. Acceleration = Change in Velocity/Change in Time Acceleration = 2 m/s / 1s Acceleration = 2m/s2

How is the velocity-time graph related to the distance traveled?

The product of velocity and time yields distance travelled if the velocity is constant for the time in question. If velocity is not constant, one must first calculate the average velocity over a given time period before multiplying it by the time involved.

When does a force change the velocity of an object?

If the object is in free-space, and any force applied over a period of time will change the velocity of an object. Force = mass * acceleration. Acceleration = velocity / time. Therefore, Force = mass * velocity/time.

When velocity changes by the same amount over each time period acceleration is?

Acceleration is constant.

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 is the value of this constant velocity if an object travels at a constant velocity for a time period of 11.31 s over a displacement of 10.55m?

Velocity = Displacement/Time =10.55m/11.31s = 0.932m/s Value of constant velocity is 0.932m/s.
