Forces

Front

What will cause an object to move?

Back

Unbalanced forces cause an object to move by creating a net force that is not zero.

Front

What is the sum of all forces acting on an object called?

Back

The sum of all forces acting on an object is called the Net Force.

Front

What is a push or pull that causes a change in motion?

Back

A push or pull that causes a change in motion is called a Force.

Front

What is the unit to MEASURE force?

Back

The unit to measure force is the Newton.

Front

What is the net force if the forces acting on an object are 400 N Up and 400 N Down?

Back

The net force is 0 N, as the forces are balanced.

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 mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change the motion of an object, while unbalanced forces cause a change in motion.

Front

What happens when two unbalanced forces act in opposite directions?

Back

The object will accelerate in the direction of the larger force.
