12/4 Forces

Front

What is a force?

Back

A force is a push or pull acting upon an object.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in motion.

Front

What is net force?

Back

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

Front

How do you calculate net force?

Back

To calculate net force, add all the forces acting in one direction and subtract the forces acting in the opposite direction.

Front

If two forces of 30 N and 50 N act in the same direction, what is the net force?

Back

80 N in the same direction.

Front

If a 10 N force acts to the right and a 10 N force acts to the left, what is the net force?

Back

0 N, balanced.

Front

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

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is an example of unbalanced forces in everyday life?

Back

A car accelerating when the driver presses the gas pedal.
