1

Force

A force is push r pull.

2

Newton

The strength of a force is measured in the SI unit called the newton (N), after scientists Sir Isaac Newton.

3

Net force

The combination of all the forces on an object is called net force.

4

Friction

The force that two surfaces exert on each other when they rub against each other is called friction.

5

Sliding friction

Sliding friction occurs when two solid surfaces slide over each other.

6

Static friction

Static friction acts between objects that aren’t moving.

7

Fluid friction

Fluid friction occurs hen a solid object moves through a fluid.

8

Rolling friction

When an object rolls across a surface, rolling friction occurs.

9

Gravity

Gravity i a force that pulls objects toward each other.

10

Mass

Mass is measured of the amount of matter in an object

11

Weight

Weight is a measure of the force of gravity on an object.

12

Inertia

Resistance to change in motion is called inertia.
