100
What is newtons third law?
With an action there is allways a reaction
200
What is momentum?
Momentum is the movement of an object measured by multiplying mass times acceleration
200
What is weight?
The acceration of an object due to gravity
200
What is friction
The tendancy of an object to not stay in motion
200
What is Gravity?
What is the force that pulls you towards you towards the center of anything that has mass ex: planet/star/object/person
200
If you throw a baseball what is the reaction?
What is the ball moves in the direction of the force exerted
300
What is relative motion?
Using referance points to determine motion.
300
What are unbalanced forces?
Forces that don't cancel each other out and change an objects motion.
300
What are the 3 types of Friction?
What is Rolling Friction,Static Friction and Sliding friction
300
What is air resistancy?
What is the force pulling you upward against gravity
300
If a car crashes and a person in not seat belted what is the reaction?
the person flies out of the car at the same speed as the car
