The amount of force a person can exert is dependent on a number of factors, including mass, acceleration, friction, gravity, and other forces. Researchers discovered that boxers’ punches can create up to 5,000 newtons of force, as reported by Live Science.

Five thousand newtons of force exceed the downward force exerted by a half-ton on the Earth’s surface. The majority of humans create significantly less force. According to the Canadian Centre for Occupational Health and Safety, a worker leaning against a solid building can generate horizontal forces of up to 675 newtons.
