First, determine the units of the quantity you’re trying to find and the quantities you have. Only use base units (meters, kilograms, seconds, charge), not compound units (Force is measured in Newtons, which are just kg*m/s 2 ). Multiply and divide the quantities until the units match the units of the answer quantity.

Is there problem solving in physics?
Problem-solving skills are clearly essential to success in a quantitative course in physics . More important, the ability to apply broad physical principles—usually represented by equations—to specific situations is a very powerful form of knowledge. It is much more powerful than memorizing a list of facts.

What is work formula?
To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd . If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.
