The don't always ! It depends on the amount of force the body is subjected to.
4 times.
Double the speed yeilds double the impact force.
An airbag reduces the force on a driver during a crash by increasing the duration of the impact, allowing the force to be spread out over a longer period of time. When a crash occurs, the airbag rapidly inflates, creating a cushion between the driver and the steering wheel or dashboard. This cushion helps to absorb some of the force and reduce the impact on the driver's body.
It depends on the amount of force force=distance*acceleration
when a car is speeding up how does the forward force and air resistance compare
There are a variety of different designs for pulleys, depending upon what you need to do with them. A pulley can be used to change the direction of a force without changing the amount of force that you apply, but there are also pulleys that do reduce the amount of force you have to use to lift something.
Electromagnetic force field.
because going up a ramp takes less force
Yes. (1/2 mass x velocity squared)
normal force, frictional force, applied force, gravitational force, air resistance force
A car absorbs the energy and force of a crash in the crumple zone.
