Bookmark or Share- How many Newtons of force would kill a person? - Physics ForumsIt is the gradient of force that would kill a person. The force has to be different in different parts of the body. If the force were sufficiently different on opposite sides of the body, or even on opposite sides of a vital organ, the person would die. The gradient of force is referred to as the stress. A stress causes a strain.
- Is Gravity Really a Force? A Look at General Relativity's PerspectiveOther virtual, pseudo or fictitious forces include Coriolis force and centrifugal force, both of which can be made to appear or disappear at will by changing reference frame. Newton's Law of Gravity is a very, very, very close approximation to General Relativity in everything other than extreme circumstances and it agrees extremely well with ...
- Hammer + Nail forces Will answer in response - Physics ForumsCalculate the magnitude of the downward force exerted by the hammer head on the nail while it is driving the nail into the wood. (Hint: By Newton’s third law, the force of the hammer head on the nail has equal magnitude to the force of the nail up on the hammer head. Ask yourself what are all the forces on the hammer head.)

- Confusion with Hailstone Collision Momentum Calculation - Physics ForumsIn a 30-s interval, 500 hailstones strike a glass window of area 0.60 m2 at an angle of 45o to the window surface. Each hailstone has a mass of 5.0 g (0.005 kg) and a speed of 8.0 m/s. If the collisions are elastic, find the average force.
- Newton's Third Law: Action & Reaction Along the Line Connecting Two ObjectsI don't think there is an issue surrounding EM radiation, as we know it has momentum and we get a force when emitting the energy and when the waves strike suitable objects. Indeed that's what I said, if you do not know that EM carries momentum/force then you might be led naively to think that electromagnetism violates momentum conservation.
