A push or a pull

• force

• inertia

• mass

• matter

Forces are measured in Newtons

• True

• False

Unbalanced forces...

• are equal & result in no motion

• are NOT equal & results in motion

• are equal and opposite

• have a net force of zero

Balanced forces...

• have a net force NOT equal to zero

• are NOT equal & results in motion

• are equal & results in no motion

• means there is acceleration or movement

The sum of all forces on an object

• acceleration

• unbalanced forces

• net force

• friction
