Force and Net Force

Front

What is a force?

Back

A force is a push or a pull on an object.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

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

Back

You subtract the smaller force from the larger force.

Front

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

Back

You add the forces together.

Front

What unit is used to measure force?

Back

The unit of force is the Newton (N).

Front

If Jennifer pushes with a force of 75 N, what force must Sam apply to create balanced forces?

Back

Sam must push with a force of 75 N toward Jennifer.

Front

What happens when the net force on an object is zero?

Back

The object is in a state of equilibrium and will not accelerate.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

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 formula for calculating speed?

Back

Speed = Distance / Time.
