Common Assessment #1 Grade 7 Force and Motion

Front

What is force?

Back

A push or pull on an object that can cause it to change its motion.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is acceleration?

Back

The rate at which an object changes its velocity.

Front

What is mass?

Back

The amount of matter in an object, usually measured in kilograms.

Front

What is the formula for calculating force?

Back

Force (F) = Mass (m) x Acceleration (a) or F = m*a.

Front

What is the unit of force?

Back

Newton (N).

Front

What does a spring scale measure?

Back

The force exerted on an object, typically in Newtons.

Front

What is friction?

Back

A force that opposes the motion of an object, often caused by contact with another surface.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass; Weight (W) = Mass (m) x Gravity (g).
