Vocabulary 1
What did Sir Isaac Newton write?
The Laws of Motion
What is energy?
The ability to do work
What is friction?
It is a force created by two things rubbing together. It slows moving things down.
False
What is speed?
The distance an object moves in an amount of time
What is velocity?
The speed and direction of an object
What will happen if an object is still and nothing is touching it?
It will stay still
Do heavy objects take more force to move than a light object?
Yes
What is force?
Any push or pull
What is a collision?
When one object runs into another
What will happen if an object is moving and nothing is touching it?
It will keep moving
an equal and opposite reaction.
In the box lab, why did the two boxes need difference force?
The heavy box has more mass, so it needs more force to move it
What is transferring?
Passing from one object to another
What is a reaction?
A response to something that has happened?
What is Potential Energy?
Stored energy
What is Kinetic Energy?
Energy in motion
In the ball lab, why did the ball sitting still not move? Why did the moving ball not slow down on its own?
Objects want to keep doing the action they are doing
How are energy and speed related?
The speed of an object reflects the amount of kinetic energy it has
What happens when objects collide?
The force of the moving object causes a transfer of energy from the first object to the second once they run into each other
In the domino lab, how did the energy transfer?
