Question

Question 1.

The validity of the four kinematic equations depends on a basic assumption made about the object being described which is:

Question 1 options:

	A) the object must be on the earth, otherwise, we must use “graviton physics”.
	B) the object has a constant acceleration, otherwise, we must use more complex equations.
	C) the object has a mass that is greater than 10-10 kg, otherwise, we must use “particle physics”.
	D) the object has a velocity greater than zero, otherwise, we must use “stationary physics”.
	E) the object has a mass that is less than 1000 kg, otherwise, we must use “mega physics”.

Question 2

A one kg steel ball and a train are dropped from a given height near the surface of the earth before they hit the ground,

Question 2 options:

	A) the train has a higher velocity, as it has a higher mass.
	B) the one kg steel ball has a higher velocity, as it has a lower mass.
	C) both hit the ground with the same velocity.
	D) the one kg steel ball has a higher velocity due to the earth’s magnetic pole.
	E) their velocities depend on the season of the year.

Question 3

On the moon, objects:

Question 3 options:

	A) fall faster than on earth
	B) fall slower than on earth.
	C) fall as fast as on earth.
	D) don’t fall at all.
	E) fall or fly depending on the mass of them.

Question 4

Two trucks are trying to drive in different directions bump to bump. The larger truck is pushing the smaller truck and moving in the +x direction. What is true about the magnitude of the force applied by each truck?

Question 4 options:

	A) The larger truck applies a greater force on the small truck
	B) The smaller truck applies a greater force on the large truck.
	C) The two trucks apply the same magnitude of the force on each other.
	D) The answer cannot be found without knowing the acceleration of the trucks.
