Q:

# How much force can a human exert?

A:

Newton's second law of motion states that the force that an object exerts is equal to that object's mass times its acceleration. The amount of force that individuals can exert is directly proportional to their mass and the speed at which they are moving.

For example, if a 45 kg person and a 62 kg person are both accelerating at 2 m/s^2, the 62 kg person exerts a greater force than the 45 kg person. Similarly, if both people are 62 kg and one of them is accelerating at 2 m/s^2 and the other at 3 m/s^2, the person accelerating at 3 m/s^2 has a greater force than the person accelerating at 2 m/s^2.

• A:

Force and mass are related by their opposite influence on acceleration: Force increases acceleration, whereas mass causes acceleration to decrease. Mass is a measure of resistance to acceleration and force is an interaction that causes acceleration, according to The Physics Hypertextbook. Both represent scientific entities acting on the rate of change in velocity of an object, defined as acceleration.
