Newton's Laws and Friction

14 terms · Newtons Laws of Motion and Friction

Gravity

The force that pulls two objects together (Usually Earth and another object).

Mass

The amount of matter in an object.

Weight

How much gravitational pull there is on an object.

Unbalanced Forces

Causes and objects motion (movement) to change.

Centripital Force

The force that causes an object to move in a circle.

Friction

The force that opposes motion. It works in the opposite direction. Ther are four types; sliding, rolling, fluid, and static

Sliding Friction

Happens when two surfaces slide over each other.

Rolling Friction

Happens when two objects roll over each other.

Fluid Friction

Happens when a solid passes through a liquid or gas.

Static Friction

Happens when objects aren't moving.

Newton's 1st Law

An object at rest tends to stay at rest, and an object in motion tends to stay in motion unless acted upon by an outside force.

Newton's 2nd Law

States that a heavier object requires more accelatation and force than a lighter one.

Newton's 3rd Law

For every action, there is an equal and opposite reaction.

Speed

How fast you are moving. It is different from velocity. To find this, you divide the distance by the time you traveled it in.
