Energy and Speed Lesson1 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 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 ghysiclally in contact with it
Noncontactforce
A principal in ghysics that states that energy can neither be created nor destroyed and that the total energy of a system by itself remains constant
Conservative 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 to change and do
Change things, grow, move Work
Objects with potential energy are not using right now but it is stored and can be used
Energy later
The higher object the object,the potential energy
More
Kinetic energy does not if 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 energy
Two forms of Mechanical Energy:
Potential 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 two objects of different masses,the greater mass accelerates more
Slowly
The pull of gravity on 2 objects depends on two factors:
Amount of matter in the object
Distance between objects
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 transformed when it. From one form to another
Changes
________________cradle is an example of transferring energy
