Intro to Forces Concept Check

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What unit is used to measure force?

Back

The unit of force is the Newton (N).

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

How do you calculate net force when forces are in the same direction?

Back

You add the forces together.

Front

How do you calculate net force when forces are in opposite directions?

Back

You subtract the smaller force from the larger force.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object does not move.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the greater force.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
