Newton's 2nd Law describes the relationships between force, mass and acceleration. What is the exact relationship between force and acceleration if mass were to remain constant?

Newton’s second law of motion seems simple enough: Push on an object of a certain mass, and it accelerates based on the amount of force and mass. A small force with a large mass results in a slow acceleration, and a large force with a small mass gives a fast acceleration. What happens when there’s no force? A force of zero on any mass gives zero acceleration. If the object is standing still, it remains still; if it’s moving, it continues to move at the same speed and direction. Keep in mind that several forces can be involved at the same time. For example, you tie a rope around a boulder and pull with all your might. There are force and mass, but the boulder doesn’t budge, so acceleration is zero. The force of friction between the boulder and the ground cancels out the force of your pull. You need a much bigger force, such as from a tractor, to move the boulder.

Force ∝ Acceleration

Explanation:

Force is directly proportional to acceleration. This is because as you increase force, the acceleration increases.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
