What is the formula for speed?
speed equals distance divided by time s=d/t
100
energy in motion
kinetic energy
100
What is a force?
a push or a pull
100
If an object is traveling at a constant speed, is that acceleration?
NO
100
What is the law of inertia?
an object at rest stays at rest, an object in motion stays in motion until acted upon by an unbalanced force
200
What is the formula for density?
density equals mass divided by volume d=m/v
200
food, batteries
chemical
200
objects are in motion are caused by
unbalanced forces
200
What is velocity?
speed and direction
200
What is Newton's 3rd law of Action-Reaction?
for every action there is an equal and opposite reaction
300
What is the formula for force?
force equals mass times acceleration F=m x a
300
moving parts
mechanical energy

How do you calculated the Net force of an object if forces are going in the same direction or opposite direction?
add-same, subtract-opposite
300
A change in speed, direction, or both is called
Acceleration
300
Force is measured in
Newtons (N)
400
What is the formula for mass?
mass is equal to force divided by acceleration m=F/a
400
energy in position
potential energy
400
objects at rest have what type of force
balanced forces
400
Speed that does not change over times is
Constant speed

What is the name of Newton's 2nd Law?
Law of Force and Acceleration
500
What is the formula to acceleration?
acceleration is equal to Force divided by mass a=F/m
500
heat
thermal energy

How do you know when work has been done?
when an object has been moved
500
What type of forces cause acceleration?
unbalanced forces (speeding up, slowing down, starting, stopping, and changing directions)
500
Less mass, less force, the greater the ______________
acceleration
