Energy And Speed Lesson 1 Flashcards
(28 cards)
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 to another object 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 principal 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
The force of attraction between two objects due to their mass
Gravity
We use energy to change
Thing grow move do work
Object with potential energy are not using right now bit 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
Cradle is an example of transferring energy
Newtons
An object 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
Medical energy
Two forms of medical energy
Potential energy kinetic energy
Is any pull
Force
Of an object depends on the force on the object
Acceleration
