The moon has less amounts of gravity than the earth does?
-
True
-
False
Correct Answer
A. TrueExplanation
The moon has less gravity than the Earth because it is much smaller and less massive. Gravity is determined by the mass of an object, so the smaller mass of the moon results in weaker gravitational pull compared to the Earth. This is why objects and people weigh less on the moon than they do on Earth.Rate this question:

Suppose the gravitational force is 10 N between two objects. If the distance between the masses is cut in half, what is the new force between the objects?
-
10 N
-
20 N
-
40 N
-
30 N
Correct Answer
A. 40 NExplanation
When the distance between the masses is cut in half, the gravitational force between the objects increases by a factor of four. This is because the gravitational force is inversely proportional to the square of the distance between the masses. Therefore, if the distance is halved, the force becomes four times stronger. In this case, since the initial force is 10 N, the new force would be 10 N multiplied by four, which is 40 N.Rate this question:

Velocity Equation - V = (__) x t
Correct Answer
gExplanation
The correct answer is g. The equation V = g x t represents the velocity (V) of an object when it is in free fall near the surface of the Earth. In this equation, g represents the acceleration due to gravity, which is approximately 9.8 m/s^2. By multiplying g by the time (t) that the object has been falling, we can calculate its velocity.Rate this question:
