Does weight increase in free fall?

An object kept in a lift which falls freely, weighs zero on the weighing machine, but its actual weight is still mg. This happens because the normal reaction force exerted on the object in the lift is equal to zero, and normal force equals to mg, which in turn equals the weight of the object.

How much force does it take to stop a falling object?

The force required to stop an object falling is always greater than its weight (which is simply the force that’s making it fall). If the slowing force is just equal to the object’s weight then it will continue at the same speed. That’s what happens when a body reaches “terminal velocity” in the atmosphere.

What falls faster a pound of feathers or a pound of rocks?

With air resistance, lighter objects land slower. A pound of rocks or a pound of feathers both weigh the same. However, the density of rocks is more than that of the feathers so the rocks have a lesser volume than an equal mass of feathers.

What do you mean by free fall and acceleration due to gravity?

Physical Science The falling of a body from a height towards the earth under the gravitational force of earth, with no other external forces acting on it is called free fall. Acceleration with which a body would fall freely under the action of gravity in a vacuum is known as the acceleration due to gravity.

What is the apparent weight of freely falling body?

The apparent weight of a freely falling body is zero. When a body falls freely, it is falling with an acceleration =g. Thus the entire gravitational force acting on it is utilized in accelerating it and hence its weight is not felt.

How do you calculate the weight of a falling object?

An object in free fall will still have a weight, governed by the equation W = mg , where W is the object’s weight, m is the object’s mass, and g is the acceleration due to gravity.

Why do feathers and bricks weigh the same?

It all has to do with buoyancy. The ton of feathers has much more volume than the ton of bricks, which is much more compact. The volume of air displaced by the material being weighed will subtract from the scale indication of any scale used to make this measurement.

Does a bowling ball fall faster than a marble?

For example, if you ask someone what would fall faster, a bowling ball or a marble, I bet a lot of folks would say the heavier bowling ball falls faster. But in fact, if dropped from a meter or so off the ground, they’d fall at the same rate. Gravity accelerates them at the same rate, so they fall at the same rate.
