What is Newton's 1st law of motion?
Object at rest stays at rest; object in motion stays in motion at a constant velocity unless acted upon by an outside force
100
What is Newton's 2nd Law?
An object's acceleration is dependent upon the object's mass and the force applied.
F = m*a
100
What is Newton's 3rd Law?
Every action force has an equal and opposite reaction force

A 5 kg object is being lifted off the ground by an unknown Tension force (on Earth). It is accelerating in the upward direction at a rate of 1.2 m/s^2. Assume g = 10 m/s^2
What is the magnitude of the force lifting the object off the ground?
F = 56N

A ball rolling along the floor doesn’t continue rolling indefinitely. Is this because it is seeking a place of rest or because some force is acting upon it? If the latter, identify the force.
Friction force slows it's movement down until it comes to a stop
