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’s 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
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
We use energy to change_____,______,_____and do_______
Things,grow,and do 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 object moves higher or lower
Change
An object’s 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 to two objects of different masses, the greater masses accelerates more ______
Slowly
The pull of gravity on 2 objects depends on two factors:_________in the objects.______between objects.
Amount of matter.Distance between objects
_________decreases as distance increases
Gravity
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
__________’s cradle is an example of transferring energy
Newton
_______the force of attraction between two objects due to their mass
