Physics Kinematics Review

Front

What is Kinematics?

Back

Kinematics is the branch of physics that describes the motion of objects without considering the forces that cause the motion.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What does it mean if an object has constant velocity?

Back

Constant velocity means that an object is moving at a steady speed in a straight line, with no change in speed or direction.

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 is the formula for calculating distance when speed and time are known?

Back

Distance (d) can be calculated using the formula: d = speed × time.

Front

What does a flat line on a distance-time graph represent?

Back

A flat line on a distance-time graph indicates that the object is at rest (not moving).

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravity only, with no air resistance.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down or decelerating.
