energy And Speed Lesson 1 Flashcards
The distance an object moves in an amount of time
Speed
The speed and direction of an object
Velocity
A change in velocity over time
Acceleration
The ability to do work
Energy
The energy that is stored inside an object
Potential energy
The energy an object has because it is moving
Kinetic 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 moment of energy from one object to another or the change of energy from one from to another
Energy transfer
A force which acts on an object without coming physically in contact with it
Non-contact force
A principale in physicas that states that energy can neither be created nor destroyed and that the energy of a system by itself remains constant
Conservation of energy
The tendency of a moving object to keep moving in a straight line or of any object to resist a change in motion
Inertia
The force of attraction between two objects due to their mass
Gravity
We use energy and do
Thing ,grow,move,do 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 If an object moves higher or lower
Change
An object kinetic energy depends on the object
Speed
The object with greater Has more kinetic energy
Mass
Is the energy an object gains when works is done on it
Mechanical energy
Two forms of mechanical energy
Political energy kinetic energy
Is any push or pull
Force
Of an object depends on the force on the object
Acceleration
If you apply the same force to two objects of different masses the greater mass accelerates move
Slowly
The pull of gravity on 2 objects depends on two factors
Amount of matter distance
Gravity As distance increases
Decreases
The pull of gravity between earth and moon causes the
Tides
Is a force that opposes the motion of one object moving past another
Friction
Energy is transferred when it From one form to another
Changes
Cradle is an example of transferring energy
Newton
