Equilibrium
An outside force must act on an object or it will continue moving at a constant velocity or remain at rest according to Newton's First Law of Motion
A force has an equal and opposite reaction according to Newton's Third Law of Motion
A contact force is applied when the surface of two or more objects interact, and is a type of force
Newton's First Law of Motion
Contact Force
Newton's Third Law of Motion
Gravitational Force
The gravitational force between Earth and any object is weight
Weight
Gravity is the acceleration of an object when the only force acting upon it is weight
Gravity
Free fall occurs when the only force acting upon an object is gravity
Free Fall
The distance would be the total length traveled in the free fall
Distance
The displacement of a person would be zero if they ran in a circular path back to the beginning, despite the distance
Displacement
The average velocity is a measure of the average time it takes to travel a certain displacement
Average Velocity
The forces that exist between the objects of a system are internal forces
Internal Force
The impulse is the product of the duration of the application and the applied force
Impulse
The net impulse is equivalent to the change in an object's momentum according to the Impulse-Momentum Theorem
Momentum
When momentum and kinetic energy remain constant before an after a collision, it is said to be an elastic collision
Elastic Collsion
When momentum remains constant but kinetic energy is lost, it is said to be an inelastic collision
Inelastic Collision
The forces between the objects within the system and objects outside of the system are external forces
External Forces
Work is the measure of energy transfer that occurs when an object is moved over a distance by an external force
Work
The Gravitational Potential Energy relies on height, mass, and gravity
Gravitational Potential Energy
Net work is the sum of the individual forces' work
Net Work
Gravitational potential energy + kinetic energy is mechanical energy
Mechanical Energy
Mechanical energy in a system remains constant as long as the only forces acting are conservative forces according to the Conservation of Mechanical Energy Theorem
Conservation of Mechanical Energy Theorem
The work-energy theorem states that the change in kinetic energy of an object equals the net work done by the forces on an object .
