Are Magnetic force fields are straight lines

The acceleration of gravity on the moon is about 1.6 m/sec2. An experiment to test gravity compares the time it takes objects to reach a speed of 10 m/sec after being dropped from rest.

Find the momentum of a 25 kg remote controlled car moving 4.0 m/s (Type your answer below, don't forget your significant figures and units!)

Apply what you know about forces to hypothesize how balanced and unbalanced forces acting on a moving car would affect the motion of the car.

A wave is incident on the surface of a mirror at an angle of 41° with the normal. What can you say about its angle of reflection?

Why does water stay in a straw if you put your finger over it?

The average speed of a runner who runs 500 m in 96 s is what?

What is the net force on a 2-kg skateboard accelerating at a rate of 2 m/s2?

Which is a consequence of the third law of thermodynamics
