What is kinetic energy?
Energy that is associated with motion.
What is a collision?
the coming together of two or more things with such force that both or all are damaged or their progress is severely impeded.
What is force?
A push or a pull.
What is matter?
What everything is made of.
What is friction?
A force that opposes motion.
What is Potential Energy?
Stored energy due to an object's position or location.
During a collision, some energy will:
transfer And transform
What is force measured in?
Newtons.
Who found out about matter?
Greeks philosophers.
Why does air friction affect a car's gas mileage?
Cars are slowed down when they stir up the air too much.
Is nuclear energy a form of potential energy?
Yes
What is the formula for collision problems?
KElost=KEf−KEi
What causes force?
Whenever there is an interaction between two objects.
What is matter made of?
Tiny particles called atoms and molecules.
Why is ice slippery?
the surface of ice when in contact with a solid object melts and creates a self-perpetuating lubricant layer.
A spring has _____ potential energy when stretched or compressed.

What happens to the total energy of the system during a collision.
Energy is converged
What can a force change?
The direction in which an object is moving.
How many gases are there?
11 elements
How can it be so hard to drag rubber across smooth glass if friction is caused by surface roughness?
In oresence of these weak bonds, if these objects are brought together they get attracted and making it hard to drag rubber across smooth glass.
What is the formula to calculate the potential energy?
mgh
How can the motion of an objects change during a collision?
Speed and direction change.
What are balanced forces?
Forces that are equal in size and opposite in direction.
Can a metal transform into a state of gas?
There are no metals as of now that are known to have gaseous phase at room temperatures.
What causes friction?
In oresence of these weak bonds, if these objects are brought together they get attracted and making it hard to drag rubber across smooth glass.
