1

Formula used to calculate force

Force= mass•acceleration

2

Contact force

When 1 object pushes or pulls on another by touching it

3

Gravity

The force of attraction between two objects

4

Friction

A force that resists motion between two surfaces that pressed together

5

Magnetic force

Force exerted between electrically charged moving particles to create a field

6

Net force

Overall force on an object when all forces are acting on it combined

7

Balanced force

When two opposite forces are EQUAL then the net force
= 0 newtons

8

Unbalanced force

When two forces act in the same direction they ADD, and when two forces act unequally inthe opppsite direction they SUBTRACT.

9

Force

push or pull that causes an object to start moving, stop moving, or change directions.
(vector quantity)

10

Inertia

The resistance of an object to change
The greater an objects mass, the greater its inertia

11

First law of motion

Objects at rest stay at rest, and objects in motion stay in motion unless acted on by an unbalanced force.

12

Newton's 2nd law of motion

Force=mass•acceleration

13

Newton's 3rd law of motion

For every action, there is an equal and opposite reaction
