Mystery
100
For every action there is an equal but opposite reaction.
What is N. Third Law of Motion?
100
The formula to find acceleration using force and mass.
What is Acceleration = Force/Mass?
100
Stored energy.
What is potential energy?
100
Forces that are equal in size and opposite in direction.
What are balanced forces?
100
The amount of matter in an object.
What is mass?
200
If force increases, then acceleration increases.
What is N. Second Law of Motion?
200
The formula to find force
What is force = mass x acceleraton?
200
Energy of motion.
What is kinetic energy?
200
Unequal forces that produce a nonzero net force.
What are unbalanced forces?
200
The measure of the pull of gravity on an object.
What is weight?
300
An object at rest will stay at rest, and an object in motion will stay in motion, unless acted on by an unbalanced force.
What is N. First Law of Motion?
300
What is the formula to find mass?
What is mass = force/acceleration?
300
Potential energy that depends on the height of the object.
What is gravitational potential energy?
300
Forces that do NOT cause a change in an object's motion.
What are balanced forces?
300
This would change if you left Earth and traveled to the moon's surface.
What is weight?
400
If mass decreases, then acceleration increases.
What is N. Second Law of Motion?
400
The formula for gravitational potential energy.
What is gravitational potential energy = height x weight?
400
Two factors that determine the amount of an object's gravitational potential energy.
What are weight and height?
400
Forces that DO cause a change in an object's motion.
What are unbalanced forces?
400
If _________ or __________ increased, then the gravitational potential energy would increase.
What are height and weight?
500
The Law of Inertia.
