Forces And Motion Lesson 1 Flashcards
_________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
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
A principle in physics that states that energy can neither be created nor destroyed and that the total energy of an 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 or 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
________________________.
Things; move; grow; work.
Objects with potential energy are not using _______________ right now but it is stored and can be used___________________.
Energy; later
The higher the object, the ____________________pontential energy
More
Kinetic energy does not ______________________if an object moves higher
An objects kinetic energy depends on the objects ________________
Speed
The object with greater___________________ has more kinetic energy
Mass
__________________ in 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 grater mass accelerates more________________________
Slowly
