Forces
Newtons Laws
Accelerated Motion
Freefall
Momentum
100
This type of force happens when objects touch eachother
contact force
100
This concept suggests that objects in motion will keep moving unless another force slows them down. (Not referring to one of Newton's laws)
inertia
100
An object has an acceleration of 20 m/s/s and a mass of 15 kg. What force must be applied?
300 Newtons
100
This the velocity reached when air resistance and acceleration due to gravity cancel eachother out.
Terminal Velocity
100
A small and large car are moving at the same speed. You try to stop them both. This car will require the most force to stop.
large car.
200
This is the category of forces that gravity, magnetic, and electric forces belong in.
field forces
200
This law states that for every action there is an equal and opposite reaction.
Newton's 3rd Law
200
An object is pushed with 1,000 Newtons of force and has a mass of 50 kg. What will it's acceleration be?
What is 20 m/s/s?
200
This is the velocity of an object falling on earth for 5 seconds without wind resistance.
49.05 m/s
200
This is the momentum of a 20 kg object moving at 10 m/s.
200
300
This type of force takes place when two objects are pushed together
compression force
300
Newton's second law states that acceleration is directly proportional to _____________.
Force
300
This will be your velocity after 10 seconds if you have a mass of 200 kg and are pushed with a 500 Newton force.
25 m/s
300
This is the amount of time an object would have to fall on earth to reach a speed of 100 m/s (no air resistance).
10.2 s
300
This is the momentum of a 10,000 gram object moving at 25 m/s.
250
400
This is the type of force that occurs when force in one direction is higher than the force in the opposite direction.
unbalanced force
400
This person discovered and first used the term "inertia".
Galileo
400
This must be your mass if you are pushed with a 100 N force and after 20 seconds are traveling at 40 m/s/s.
50 kg
400
This is the amount of time an object would have to fall if it were traveling on earth at a speed of .2 km/s. (No air resistance).
20.4 s
400
This is the momentum of a 200,000 cg object moving at a speed of 20 m/s.
40
500
This type of force takes place when objects are twisted.
torsion
500
In order for Newton's first law to apply an object must be in this state.
Mechanical equilibrium
500
This would be the force applied to an object if it has a mass of 20 pounds (1 pound = 0.45 kg) and after 10 seconds is traveling at 50 m/s.
45 Newtons
500
This is the velocity an object would have if it fell on earth for an hour (no air resistance).
35,316 m/s
500
This is the mass (in kg) of an object with a momentum of 200 that has a velocity of 100,000 m/h
