The mass would stay the same, but the weight would be only 16.5%.
Explanation:
Mass is the amount of "matter" in an object, which stays the same everywhere. Weight is the force acting on an object by gravity, which changes depending on nearby bodies. In this case, weight on the moon is 16.5% of that on Earth.
Answer:
D
Explanation:
It has the most "potential" to fall down because it is the highest relative to the ground.
Answer:
D. accelerated
Explanation:
According to Newton's first law of motion, an object always remains in its state of rest or in uniform motion until an external unbalanced force is acted upon the object. This means if an external unbalanced force is acted on the object, it will come to a non-uniform motion i.e., an accelerated motion.
Let me first get you clear that uniform motion is determined by a constant velocity and a state of rest is considered by a zero velocity or speed. But, here we have an unbalanced force acting on the object. This means the object will change its velocity and hence, it has an accelerated motion.
Answer:
(D) is correct option.
Explanation:
At a particular time, the potential energy of a rock is 500 J and its kinetic energy is 600 J.
It is required to find the mechanical energy of the rock. Mechanical or total energy is the sum of kinetic and potential energy. So,
TE = K+ P
TE = 500 J + 600 J
TE = 1100 J
So, the total mechanical energy of a rock is 1100 J. Hence, the correct option is (D).
