What are the 2 types of Force? (give ex.)
Contact Force > Pushing a car up a hill and kicking a ball Non-Contact Force > Gravitational Force > Magnetic Force
What are the types of contact force?
Applied force, Spring force, Drag force, frictional force, and Normal force
What are the types of non-contact force?
Magnetic force, electric force, and gravitational force
What is the first law of motion? (explain what it is)
Law of inertia - A tendency of an object to resist change in its motion
What is the equilibrium
When a non-zero net force is acting on an object is balance by a single force.
What is the Formula for the Law of Acceleration?
F = ma
What are the key concepts of action-reaction?
> Every action force is match by a reaction force These forces are equal in magnitude and opposite in direction
