Speed
distance traveled per unit of time
Energy
the ability to do work or cause change; can be changed into different forms and can move between objects
Velocity
the speed and direction of moving objects
Force
a pull or push that is applied to an object
Mass
the amount of matter in an object
Gravity
a force that exists between any two objects that have mass (related word: gravitational)
Stability
a factor that determines if an object can stay upright or remain in the same position
Mechanical energy
energy that an object has because of its motion or its position
Acceleration
a change in the velocity (speed, direction, or both) of a body (related word: accelerate)
Kinetic energy
the energy an object has because of its motion
Inertia
an object’s resistance to a change in motion
Motion
a change in the position of an object compared to another object (related term: move, movement)
Friction
a force that opposes the motion of a body across a surface or through a gas or liquid
Potential energy
the amount of energy that is stored in an object; energy that an object has because of its position relative to other objects
Net force
the resulting force determined by combining all of the forces acting on an object
