If a person who weights 450 lbs were to freefall, does that mean that they would be going 450 mph? I know I learned this in high school but I forgot..

The speed that you fall is virtually the same for all people; the reason it is not exactly the same is because because different body types would experience different amounts of drag. When you go sky diving after a very short time your velocity stabilizes and you are at what is called terminal velocity. In the position you see people sky dive in (facing the ground with arms and legs extended) terminal velocity is right about 120 miles per hour.

No. The weight of a person is a factor of the force the person hits the ground.
F = ma
F - force.
m - mass.
a - acceleration.
The acceleration here is due to the force of gravity which is 9â81m/s². All fallen object travel at the same speed.

sell objects fall toward the earth with the same acceleration. How fast they fall depends on how long they have been falling. It has nothing to do with their weight.
Because of wind resistance, someone that has been falling a long time might reach what is called terminal velocity. But that has more to do with the shape than the weight.

No. When a person falls, the speed increases the farther they fall. Unless they're eating on the way down, the weight stays the same.

No all objects regardless of weight fall at the same speed

no. an object falls at 9.8 meters per second. an object acc. depending on the mass. how much matter something takes up

they would be going at -9.8 m/s^2
