What is velocity?

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position. It includes both speed and direction.

Front

What is the formula to calculate speed?

Back

Speed = Distance / Time

Front

If a cyclist moves in a circular path at a constant speed, what happens to their velocity?

Back

Velocity changes due to change in direction.

Front

What does a constant speed graph look like?

Back

A straight line on a distance-time graph indicates constant speed.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does it mean if an object is standing still?

Back

An object is standing still if its position does not change over time.

Front

How do you calculate the speed of an object?

Back

Speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is the unit of speed?

Back

The unit of speed is typically meters per second (m/s).

Front

What does a decrease in speed indicate?

Back

A decrease in speed indicates that an object is decelerating or slowing down.
