TermDefinition
The ability to do work Energy
the ability to make something move (potential and kinetic energy) Mechanical Energy
the energy that an object or substance has because of its position or condition Potential Energy
the energy that an object or substance has because of its motion Kinetic energy
the change in the objects position Motion
fixed, unmoving object; needs to be fixed in position Reference point
how far an object travels: the amount of space between two points Distance
The distance an object travels in a specific time Speed
the speed of an object at any one moment Instantaneous speed
the speed an object travels during an entire trip Average speed
the distance an object moves over a given amount of time in a certain direction Velocity
a change in velocity during a period of time Acceleration
a push or pull applied to an object in order to change its velocity Force
a force that keeps an object from moving against other objects Friction
mass and velocity Momentum
An object tends to stay at the same velocity unless another force causes it to change; an object at rest tends to stay at rest 1st law of Motion
resistance to a change in motion Inertia
the pull of one object on another object Gravity
resistance caused when two objects move against each other Friction
Force is equal to an object’s mass and the acceleration of the object Mass ✘ acceleration = force 2nd Law of Motion
When one object everts a force on a second object, the second object reacts by exerting an equal force back on the first object ; the law "action and reaction" 3rd Law of motion
