What is the net unbalanced force?
100
The equation F=ma is the mathematical representation of this law.
What is the second law of motion?
100
When given the mass and the acceleration, looking for the net force.
What is F=ma?
100
When the acceleration is 4 m/s2 and the mass is 40 kg, this is the net force.
What is 160 N?
200
The force causing an object to move
What is the applied (or horizontal) force?
200
The force that is equal to force weight on a level surface.
What is the normal force?
200
Also known as the law of inertia.
What is the first law of motion?
200
When give the net force and mass, and asked for the acceleration?
What is F=ma?
200
The net force when the frictional force is 150 N and the horizontal force is 200 N.
What is 50 N?
300
The force due to gravity
What is the force weight?
300
If the object is traveling at a constant velocity, this equals the applied or horizontal force.
What is the frictional force?
300
The law which explains the amount of force two colliding objects will each experience.
What is the third law of motion?
300
When given the acceleration, the mass, and the horizontal force, asking for the frictional force.
What is F=ma, and Fnet=Fh-Ff?
300
The net force when a 25 kg object has a horizontal force of 100 N, and an acceleration of 4 m/s2.
What is 100 N?
400
The force enacted on an object by the surface supporting it
What is normal force?
400
If the object is in freefall, this is the only force acting upon the object.
What is the force of gravity?
400
This law is use to explain why objects slide to the floorboard in a stopping vehicle.
What is the first law of motion?
400
When given mu and the frictional force, looking for the normal force.
What is mu=Ff/Fn?
400
The acceleration when a 50 kg object has a mu of 0.2 and a horizontal force of 100 N.
What is 0.04 m/s2?
500
The speed at which a falling object's air resistance equals its acceleration
What is terminal velocity?
500
The force that resists motion
What is the force friction?
500
This law applies to finding the acceleration of two objects with different masses, but the same force enacted upon them.
What is the second law of motion?
500
When given the mu, and the frictional force, solving for the mass.
What is mu=Ff/mg?
500
When the horizontal force is 150 N, the acceleration is zero, and the mu is 0.25, this is the mass.
