Question
Which type of mechanics deals with objects moving at speeds close to the speed of light?
A) Quantum
B) Classical
C) Relativistic
The magnitude of the gravitational field experienced by a planet in orbit around the Sun is:
A) proportional to the mass of the planet
B) proportional to the mass of the sun
C) proportional to the distance between the planet and the sun surface
D) Inversely proportional to the distance between the planet and the sun surface
Consider what happens when you jump up in the air.
A) You are able to spring up because the force of the earth upward on you is stronger than the downward force you exert on the earth.
B) When you jump up the earth exerts a force on you and you exert a force on the earth. You go up because the forces are proportional to the masses of the source and therefore the earth
Explanation / Answer
C)Relativistic
D)Inversely proportional to the distance between the planet and the sun surface
D) Since the ground is stationary, it cannot exert the upward force necessary to propel you into the air. Instead, it is the internal forces of your muscles acting on your body itself which propels the body into the air.
A) Your weight would change, but your mass would not change
