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 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 in contact with it
Non-contact force
A principle in physics 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 force of attraction between two due to their mass
Gravity
We use energy to change things
Grow ,move , do work
object with potential energy are not using ____ right now but it is stored and can be used _____
Energy
Later
The high the object the _____ position energy
More
Kinetic energy does not ______ if an object moves higher or lower
Change
An object’s kinetic depends on the object’s ____________
speed
The object with greater ________________ has more kinetic energy
Greater
Mass
_________ is the energy an object gains when work is done on it
Mechanical energy
Two former 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 to two objects of different masses the greater mass accumulates more
________
Slowly
The pull of gravity on 2 objects depends on two factors
Amount of matter Distance
Gravity __________as distance increases
decrease
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 transforming energy.
Newton’s
The tendency of a moving object to keep moving in a straight line or of any object to resist a change in motion
Inertia
