100
forces on an object that causes change in the motion of the object
What is a balanced force?
100
a unit used to measure energy
What is joule?
100
forces on an object that causes change in the motion of the object
What is unbalanced force?
100
the measurement of the rate of change of position with respect to the time
What is speed?
100
something measured that can change
What is a physical variable?
200
when its staying at a resting point at the top
at what point does a roller coaster has the most potential energy?
200
controls the amount of change that can occur with in an system
What is energy?
200
an object in motion will stay in motion and a object at rest will stay at rest unless acted on by an unbalanced force
What newtons first law of motion?
200
the path that an object is moving or facing
What is direction?
200
the force of an object is equal to its mass times its acceleration
What is newtons second law of motion?
300
for every action theirs an opposite and equal reaction
What is newtons third law of motion?
300
an energy transform is a change of energy from one type to another kinetic to potential or potential to kinetic
What is energy transform?
300
a force that attracts or repels objects toward or away from each other
What is magnetism?
300
a system is a group of interacting or independent elements forming a complex whole
What is a system?
300
both cars are traveling at the same speed
how does two different speeds of a car compare?
400
mechanical energy is the sum of all energy potential and kinetic with in a specific systems
what is mechanical energy?
400
kinetic energy is energy of motion
What is kinetic energy?
400
gravity is pushing the cup down
if a cup is sitting on a table whats happening?
400
gravity is the force that pulls objects towards each other
What is gravity?
400
for every action theirs and equal and opposite reaction
a person blows into a balloon what law is this?
500
something pushing against an object
What is a force?
500
Potential energy is energy that is stored in a system or in a object
What is potential energy?
500
a point used for a comparison to determine distance direction and speed
What is a reference point?
500
it looks like you were moving backwards because the other car was moving forward
What would it look like if you were sitting still in a parking lot and another car pulls up beside you ?
500
because of the carpet it causes friction
What happens to block if it is thrown across the floor and it slowly losses its speed what is causing the block to slow down?
