Witryna26 lut 2024 · So, we now know that a force plate records both the force that we apply to the ground when we contract our muscles and how long we apply any force for. Multiplying force (how hard we push or pull something) by time (how long we apply this force for) gives 'impulse' and this is the driver of all movement. Impulse is directly … WitrynaThe quantity of force (F) × time (t) is known as impulse. Impulse is equal to the change in momentum, F×t = m×Δv.
