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 over time
Motion
The 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 form to another
Energy transfer
A force which acts on an object without coming physically in contact with it
Non contact force
A priceiple in physics that states that energy can neither be created nor destroyed and that the total energy of system by itself remains constant
Conservation of energy
The tendency of a moving object to keep moving in a straight line of any object to resist change in motion
Inertia
The force of attraction betweeen two objects due to their mass
Gravity
We use energy to change
Things,grow,move,work
Objects with potential energy are not using _ right now but it is stored and can be used
Energy and later
The higher the object the _ potential energy
More
Kinetic energy does not __ if an objects moves higher or lower
Change
An object’s kinetic energy depends on the objects
Speed
The objects 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 object
Acceleration
If you apply the same force to two objects of a different masses, the greater accelerates more
Slowly
The pull of gravity on 2 objects depends on two factors
Amount in the objects distance between objects
Gravity___ as distance increases
Decreases
The pull of gravity between earth and moon causes the
Tides
Is a force the opposes the moition of one form to another
Friction
Energy is transferred when it _ from one form to another
Changes
Cradle is an example of transferring enrgery
Newtons
