Forces and motion test review

Front

What is speed?

Back

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

Front

What does a constant speed graph look like?

Back

A constant speed graph is a straight line that slopes upwards, indicating that distance increases steadily over time.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

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 when an object is at rest?

Back

An object is at rest when it is not changing its position relative to a reference point.

Front

What is acceleration?

Back

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

Front

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

Back

A horizontal line indicates that the object is not moving; it is at rest.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is a force?

Back

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

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.
