How do you calculate the force of a falling object?

Question

Let's say there is an object weighing about 910 kg. It falls from a distance of 30 cm. Assuming the only force acting on the object is gravity, what would the force of the 910 kg object be when it hits a concrete floor.

Answer 1

You don't have enough information to calculate the force on impact. In order to do this, you'd need to be able to measure the amount of time from impact to stop (which will be small, but non-zero), or the total distance that the object travals from impact to stop (again, this will be a small, non-zero number.)

From there, you would determine the acceleration after impact, which can in turn be used to determine the force.

Marbledog's answer above is the force of gravity acting on the object, which is NOT the same as the force on impact, as it does not account for the deceleration of the object after it hits the ground.

Calculate Force Of Falling Object

Answer 3

The only way to find the force exerted during the collision is to actually measure it directly with some sort of force sensor.

You could estimate the average collision force if you just measure the time interval of contact between the object and floor on its first bounce and use the impulse-momentum theorem.

Answer 4

this, in this case, is a free fall as the ball is falling with terminal velocity=0 n no force acting on it with exception of gravity. so the weight or distance doesn't matter and the acceleration of the moving object will be equal to gravity which is approximately 10 meters per second squared (9.8).
F=ma
910*10 = 9100 N

Answer 5

F = ma

Where
F is force,
m is mass,
a is acceleration. Acceleration due to Earth's gravity is 9.81m/s² for any object.

So the force of gravity acting on the object is:
F = 910kg * 9.81m/s² = 8927.1N (Newtons, the SI unit of force).

Answer 6

F = ma

More important than the 'force' is its Kinetic Energy level when it hits the floor.

KE = 1/2mv^2
