• Speed

Answer: Distance traveled per unit time

• Velocity

Answer: Speed in a given direction

• Acceleration

Answer: rate of change of velocity

• Distance

Answer: How far an object moves

• Displacement

Answer: the change in position of an object

• Force

Answer: A push or a pull

• net force

Answer: The combination of all forces acting on an object

• Newton's first law of motion

Answer: an object in motion will remain in motion unless acted upon by another force

• Mass

Answer: the amount of matter in an object

• Inertia

Answer: the tendency to keep the same motion

• Newton's Second Law of Motion

Answer: The acceleration produced by the net force on an object is proportional to the net force, and inversely proportional to the mass

• Newton's Third Law of Motion

Answer: For every action there is an equal and opposite reaction. States that whenever one object exerts a force on a second object, the second object exerts a force of the same magnitude in the opposite direction on the first object.
