Front

What is average velocity?

Back

Average velocity is the total displacement divided by the total time taken. It is a vector quantity, meaning it has both magnitude and direction.

Front

How do you calculate average velocity?

Back

Average velocity = (Final position - Initial position) / (Final time - Initial time).

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the straight line distance from the starting point to the endpoint.

Front

What is average acceleration?

Back

Average acceleration is the change in velocity divided by the time over which the change occurs.

Front

How do you calculate average acceleration?

Back

Average acceleration = (Final velocity - Initial velocity) / (Time taken).

Front

What does a negative average velocity indicate?

Back

A negative average velocity indicates that the object is moving in the opposite direction to the defined positive direction.

Front

What is the significance of a zero average velocity?

Back

A zero average velocity means that the object has returned to its starting position, resulting in no net displacement.

Front

What is the formula for calculating displacement?

Back

Displacement = Final position - Initial position.

Front

What is the relationship between velocity and acceleration?

Back

Velocity is the rate of change of displacement, while acceleration is the rate of change of velocity.
