Newton's First Law
Objects tend keep doing what they're doing
Objects at rest stay at rest
Objects in motion stay in motion
Balanced forces and unbalanced forces
Unbalanced forces lead to acceleration
Types of forces
Contact Forces include frictional, tension, normal, air resistance, applied, and spring forces.
This includes things like pushing and pulling an object. And the friction and air resistance acting on moving objects
Action-at-a-Distance Forces include gravitational, electrical, magnetic forces. Most of the time gravitational forces will be in play.
Almost always this is gravity
Newton's Second Law
Forces that are balanced have an acceleration of 0m/s/s
F net = m * a
1 Newton = 1kg * 1 m/s/s
Newton's Third Law
For every action, there is an equal and opposite reaction
Two objects interacting will exert force on each other
The direction of the force on the first object is opposite to the direction of the force on the second object.
Mass vs Weight
Mass is defined as the amount of matter in an object. Unlike weight, it is not affected by gravity and it still exists in no gravity.
This meaning, if you weighed 80kg on Earth, your
on the moon would be 80kg (same with any place).
Weight is a force, a gravitational attraction the object towards another object with a gravitational pull. Your weight depends where you are.
If you weighed 80kg on Earth, you would weight dramatically less on the moon. Or in space you would be weightless (0kg).
