Force = Mass x Acceleration
What is Newton's Second Law?
The force that weighs you down differently on the moon verses on Earth.
What is gravity?
This is the reason for friction?
What is the interaction between surfaces?
An object at rest stays at rest or an object in motion stays in motion at constant velocity with no unbalanced forces.
What is Newton's First Law?
The force that opposes motion between two surfaces that are touching is this.
What is friction?
SI Unit for speed or velocity
What is meters per second (m/s)?
The amount of matter in an object
What is mass?
For every force, there is an equal force in the opposite direction.
What is Newton's Third Law?
A force is a ____ or a _____.
What is a push or a pull?
SI Unit for Acceleration
What is meters per second squared (m/s2) ?
An object has a mass of 10 kg and we want to know its weight. (g = 9.8 m/s2) Use Newton's 2nd Law!

What is the same value?
or
What is 10 kg?
The reason when the same force is applied, a lighter mass has a larger acceleration than a larger mass.
What is Newton's Second Law?
The upward force that opposes gravity when an object is floating in water or another fluid.
