Force and Motion STAAR Questions

Front

What is force?

Back

A force is a push or pull acting on an object, which can cause it to accelerate, change direction, or change shape.

Front

What is motion?

Back

Motion is the change in position of an object over time.

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 at which an object's velocity changes over time.

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.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is friction?

Back

Friction is a force that opposes the motion of an object in contact with a surface.
