Definitions
A push or a pull
What is a force?
For every action there is an equal an opposite reaction
What is Newton's 3rd Law?
You add to find the net force
What is if the forces are acting in the same direction?
Stored energy
What is potential energy?
A force that pulls things toward the center of the Earth
What is gravity?
The resistance of an object to change position, direction, or speed
What is inertia?
You subtract to find the net force
What is if the forces are acting in the opposite direction?
Energy of motion
What is kinetic energy?
Two equal forces acting in opposite directions
What are balanced forces?
F = ma
What is Newton's 2nd Law?
The net force is zero
What is a balanced force?
You have the most potential energy on a rollercoaster.
What is the top of the highest hill?
The total forces acting on an object
What is Net Force?
An object in motion stays in motion and an object at rest stays at rest unless acted on by an unbalanced force
What is Newton's 1st Law?
The object will move left
What is if the net force is greater to the left side?
You have the least potential energy on a rollercoaster
What is at the bottom of the hill?
The forces that cause a change in direction, position, or speed
What are unbalanced forces?
It is important to wear a seatbelt because of this law.
What is Newton's 1st Law?
The net force is greater on one side
What is an unbalanced force?
Potential energy decreases when this happens
What is when kinetic energy increases?
