Energy And Speed Lesson 1 Flashcards
The distance an object moves in an of time
Speed
The energy that is stored inside an object
Potential
The energy an object has because it is moving
Kinetic
The speed and direction of an object
Velocity
A change in velocity over time
Acceleration
The ability to do work
Energy
The process of an object changing position over time
Motion
Force that results from the interaction of two objects in contact with each other
Contact force
The movement of energy from one object to another or the change of energy from one form to another
Energy transfer
A force which acts on an object without coming physically I contact with it
Non-contact force
Principal that states energy can neither be created nor destroyed, and that total energy of a system itself remains constant
Conservation of energy
The tendency of a moving object to keep moving in a straight line or object to resist change in motion
Inertia
The force of attraction between two object to their mass
Gravity
We use energy to change _________,__________,___________and do,_______________
Things grow move work
Object with potential energy are not using ______right now but it is stored and can be used ___________
Energy , later
The higher the object the _______ potential energy
More
Kinetic energy does not ___ an object moves higher or lower
Change
An object’s kinetic energy depends on the object’s ________________
Speed
The object with greater _______ has more kinetic energy
Mass
____________________________________________________is the energy an object gains when work is done on it
Mechanical

Potential, kinetic
__is any push or pull
Force
