Newton’s Laws of Motion

what is the first law also known as?

the Law of Inertia

What is Newton's first law?

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Example of an unbalanced force

gravity, friction, ect.

inertia

The tendency of an object to resist a change in motion

what is Newtons second law also known as?

law of force and acceleration

What is Newton's second law?

Force = mass x acceleration

what is the formula for force?

F=ma

what is the formula for acceleration?

a=f/m

mass

the amount of matter in an object and measure of inertia

weight

the force of gravity on an object

what is the formula for gravity?

mass x acceleration due to gravity (9.8 m/s2)

What is Newton's third law?

For every action there is an equal and opposite reaction

if equal and opposite forces act on the same object, what is the net force?

0

Momentum

The product of an object's mass and velocity

an object with larger momentum=

harder to stop

formula for momentum?

mass x velocity

law of conservation of momentum

if no net force acts on a system, then the total momentum of the system does not change
