Mass of a body and its speed are needed to calculate kinetic energy. Kinetic energy of an object = mv2/2 This formula is useful only when object's speed is much less than speed of light.

Basically, the upward force has to counteract the downward force of gravity. Thus, the upward force has to be equal to the object's weight. There is not much calculation to do here; just use the standard formula for weight: weight = mass x gravity Under normal Earth gravity, you can use 9.8 for gravity; thus, every kilogram has a weight of about 9.8 newton, and therefore requires an upward force of 9.8 newtons to keep it in balance.

You cannot use surface area to calculate density. Density is a calculation comparing TOTAL area and weight of an object. In short you must use the total volume of the object when calculating the density.

When we calculate the net force acting on the object in these situations, we use the formula… FNET = Fa + Ff When you want to calculate the acceleration of an object, always use the net force acting on it. FNET = ma We need to think of the net force as the force pushing down on the scale causing it to give a reading. for example- The elevator pushing up on me will make me push down on the floor (Newton's 3rd Law). We will show this by making the acceleration (3.0m/s2) a negative value. The formula for this would look like this… FNET = Fg + Fa

A spring device can only measure an object's weight. In order to find its mass, you then have to either compare its weight with the weight of a known mass, or else use the value of gravitational acceleration to calculate the mass from the weight.
