Match the definition:

The ability to cause a change in an objects motion.

• Force

• Inertia

• Vector

• Gravity

Match the definition:

The resistance of an object to change its motion.

• Force

• Inertia

• Gravitational Mass

• Momentum

Match the definition:

A measure of an object's resistance to change its motion.

• Force

• Gravitational Mass

• Friction

• Inertial Mass

Match the definition:

A diagram of all the forces acting on an object (including direction).

• Motion Diagram

• Velocity vs. Time Graph

• Free Body Diagram

• Hamiltonian

Match the definition:

An object in motion will maintain a constant velocity unless acted on by a net external force.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• Conservation of Momentum

Match the definition:
An object's acceleration is equal to the net force acting on the object divided by its inertial mass.

 $\overrightarrow{a\ }\ =\ \frac{\Sigma\ \overrightarrow{F\ }}{m}$  

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• Superposition Principle

Match the definition:

A field force acting between the centers of mass of two objects proportional to the mass of the objects.

• Normal Force

• Force of Gravity

• Magnetic Force

• Inertia

Match the definition:

A contact force preventing objects from moving through each other that is always normal (perpendicular) to the surface in contact.

• Force of Gravity

• Force of Static Friction

• Normal Force

• Tension

Match the definition:

A force that is proportional to the normal force and comes both kinetic and static varieties.

• Tension Force

• Newton's 2nd Law

• Newton's 3rd Law

• Force of Friction

Match the definition:

For every force object 1 applies to object 2, there is a force object 2 applies to object 1. These forces have the same magnitude but opposite directions.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

• Resistive Force
