Front

What is velocity?

Back

Speed in a specific direction.

Front

What is the formula to calculate the velocity of an object?

Back

Velocity = Displacement / Time.

Front

What is acceleration?

Back

The rate of change of velocity over time.

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What does a dot graph represent in kinematics?

Back

A dot graph shows the position of an object at different times.

Front

What does it mean if an object is slowing down?

Back

Its velocity is decreasing over time.

Front

If a cheetah travels 75 m to the West in 3 s, what is her velocity?

Back

25 m/s West.

Front

How do you determine the time it takes for an object to fall a certain distance?

Back

Use the formula: Time = sqrt(2 * Distance / g), where g is the acceleration due to gravity (9.8 m/s²).

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.8 m/s².

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).
