inertia
gravity
What is Newton's FIRST law?
An object that is a rest will remain at rest, and an object in motion will stay in motion unless an outside force acts upon it
If a force increases, so will mass and acceleration. If mass or acceleration decrease, so will force.
For every action, there is an equal and opposite reaction
What is Newton's SECOND law?
For every action there is an equal and opposite reaction
If force increases, so will mass and acceleration. If mass or acceleration decrease, so will force.
An object at rest will remain at rest, and an object in motion will stay in motion unless an outside force acts upon it.
What is Newton's THIRD law?
For every action, there is an equal and opposite reaction
An object at rest will remain at rest, and an object in motion will stay in motion unless an outside force acts upon it.
If force increases, so will mass and acceleration. If mass or acceleration decrease, so will force.
Multiplying the object's mass and velocity determines what?
speed
momentum
force
weight
