Gravity
What is the rate of acceleration of gravity?
9.8 m/s^2
What is Newton's second law?
Net Force = Mass x Acceleration
What is sliding friction?
Resistance encountered when two objects in direct contact move against each other
What is kinetic energy?
What is acceleration?
What does GPE stand for?
Gravitational Potential Energy
What is Newton's First law?
An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force
Give an example of fluid friction
What is potential energy?
The potential energy
What is a reference point?
The point of view
What is the difference between weight and mass?
Weight is the amount of force gravity exerts on you while mass is the amount of matter you have.
What is Newton's Third Law?
For every action (force) in nature there is an equal and opposite reaction
What is rolling friction?
The force that resists one solid rolling on another
Does GPE increase the higher up you go?
Yes
If someone said a cow in a wagon isn't moving while the wagon is moving, what could the reference point be?

A ball is thrown downward with an initial speed of 9 m/s. After 3 seconds, the ball's velocity is ___ m/s.
38.4 m/s
What is Newton's law of universal gravitation?
All objects with mass attract other objects
What direction does friction go compared you your motion?
In the opposite direction
A wagon of mass 0.5 kg is moving at a speed of 4 m/s. What is its kinetic energy?
4 J
A line with a positive slope
What is Gravitational Potential Energy?
Gravitational energy or gravitational potential energy is the potential energy a massive object has due to its position
