Answer:
It fell down
Explanation:
Because its heavy. The gravity pull down the stone into the ground
Explanation:
the work a force does is measured in newton-meters (N-m), which use the symbol of J. Time (t) is expressed in Second. Power (P) is expressed in Watt (W).
Answer:
Density is the mass over volume.
Explanation:
It tells us how much matter is there in a certain measurement of volume.
