Q:

# What two forces determine whether an object floats or sinks?

A:

The two forces that determine whether an object floats or sinks are buoyancy and pressure. Buoyancy is determined by the density of the object and the density of the medium.

The property of being able to float or sink in mediums does not depend on the weight of the object. For an object to float, it must be less dense than the medium it is put in, creating a positive buoyant force. Pressure from the water creates an upthrust force that also determines whether an object sinks or floats. If the upthrust force is great enough, an object could float even though it would generally sink.

Heat measures the movement of molecules in an object, while temperature measures the average energy or heat generated by the molecules in an object. The faster the molecules move, the more heat they produce and the higher their temperatures become.

To calculate the amount of work applied to a given object, multiply the force acting upon the object by the object's displacement, and multiply that total by the cosine of the angle between the force and displacement. Use joules as the unit of measurement for work.

The equation for calculating kinetic energy is KE = ½mv², where m is the mass of the object and v is its velocity. When an object is at its highest, it has the most potential or stored energy; at its lowest point, it has its most kinetic energy.
