First Law
This law says objects at rest stay at rest unless acted on
What is Newton’s First Law?
The formula for Newton’s Second Law
What is F=MA
Every action has this
an equal and opposite reaction
a seatbelt stopping you in a crash is an example of what law?
Newtons first law
A push or a pull
Force
The tendency of an object to resist change in motion
What is inertia?
If Force increases, acceleration does this
increases
When you jump, you push down on the ground and the ground does what
pushes back
Kicking a soccer ball harder makes it go faster- this is what law
Newtons Second law
Object change in motion
Acceleration
A soccer ball won’t move until this happens
What is a force is applied?
If mass increases, acceleration does this
decreases
Rockets move forward because gases do this
push bakward
A balloon flying around the room when released
Newtons third law
Amount of matter in an object
Mass
Why you lurch forward when a car stops suddenly
What is inertia?
mass affects acceleration
swimming works because you push water this way
backwards
Why is it harder to push a full shopping cart?
A force that opposes motion
Friction
An object moving in space will keep moving unless this acts on it
What is an unbalanced force?
Unit to measure force
Newton
Name both forces in a book siting on a table
gravity and contact force
Why you feel pushed back when a car speeds up
Inertia
Forces gravitational pull on a person is called
Weight
