Exam Review: Motion

Front

What is motion?

Back

Motion is the change in position of an object over time relative to a reference point.

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

What is a force?

Back

A force is a push or pull acting upon an object, measured in newtons (N).

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as the product of force and time (Impulse = Force × Time).

Front

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

Back

A flat line indicates that the object is at rest and not moving.

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope indicates that the object is moving quickly.

Front

What is a velocity-time graph?

Back

A velocity-time graph shows how the velocity of an object changes over time.

Front

What does a constant positive slope on a velocity-time graph indicate?

Back

A constant positive slope indicates constant acceleration.
