The net or resultant force acting on an object is equal to the rate of change of momentum. We can therefore say that because a net force causes an object to change its motion, it also causes its momentum to change with it.
Answer:
A
Contact forces are forces that require the actual contact (touching) of two pieces of matter. ... A field force is a force that works at a distance. No touching is required. Gravity is a good example of a field force, because it works whether or not an object is touching something or touching nothing at all.
The answer is 330 meters per second! hope this helped! please crown me if it did when you can!
Answer:
The force used is 160 N, and the power used is 133 W.
Explanation:
Because the formula for force is Work/Distance, the answer in that case would be 800J/5m, and that would give you an answer of 160 N. For Power, the formula is Work/Time, and for that the expression would be 800/6, and that would give you 133 W as the power used.
