Force
100
kinetic energy is the energy of what?
motion
100
what is a balanced force?
equal forces
100
what is velocity?
speed and direction
100
True or False: An object in motion will stay in motion.
What is True
100
what is force?
a push or pull
200
what is potential energy?
stored energy; when an object is not moving?
200
what is an unbalanced force?
unequal forces
200
what is acceleration?
A. speeding up
B. slowing down
C. both
both acceleration can be increasing speed or decreasing speed
200
A rocket taking off is an example of which of Newton's laws?
A.1st
B.2nd
C.3rd
D.88th
What is 3rd
200
what type of force is there less of on the moon?
Gravity
300
which has more potential energy? A rock on the edge of cliff or a pencil on the edge of a desk? Why?
the rock, because the higher something is the more potential energy it has.
300
which type of force will cause objects to move? why?
unbalanced force, because the force will move on one side because the force is not equal
300
what is Mass?
the amount of matter in an object
300
Which of Newton's laws states: That an object at rest will stay at rest and an object in motion will stay in motion at a constant velocity, unless acted upon by an unbalanced force.
A.1st
B.2nd
C.3rd
D.D.U.I.
What is 1st
300
Force is measured in what?
Newtons
400
what two things affect how much potential or kinetic energy something has?
the height of an object and the mass. speed could also count for kinetic energy
400
What is the net force of an object?
the total amount force on an object?
400
what factors affect the amount of damage in a collision and why? name at least 2
speed, mass, friction, inertia, direction, material of object.
400
Which of Newton's Laws states: That for every action there is an equal and oppostite reaction.
A.1st
B.3rd
C.2nd
D.The law of Harrison Ford
What is 3rd
400
what type of force slows objects down?
Friction
500
At which point is the highest potential energy and the highest kinetic energy?
point C has the most potential and Point A has the most Kinetic
500
calculate the net force on this object?
net force is 0 because the force is the same on both sides.
500
what material could be used to keep a phone from from breaking. The material is on the phone case.
rubber, silicone, bendable plastic, and others
500
what is the formula for Newtons second law about acceleration.
Force = mass X Acceleration F=m X a
500
the type of force that pulls you forward
inertia
