This depends on the path of the object and what information you have.
You could be looking at conservation of kinetic and gravitational potential energy. Total energy must be the same at all times. ...

Student should calculate the moments about the pivot point (from diagram recognise this is the centre of the see-saw) for each child. Using the equation, moment = mass x acceleration x distance from pivot...

The two decayed particles will form identical spirals but in the opposite direction to one another, as they will have to be oppositely charged to preserve the overall charge. The spiral patterns will be i...

Young's Modulus is defined as the ratio of stress to strain. E = stress/strain. Stress is the force per unit area, F/A. By substitution, we can see that E = F/(A x strain). Rearranging gives F = E x A x s...

The nucleus is made up of protons and nuetrons, which means there is an electric repulsion. The nucleus is held together by somethign called the strong nuclear force. This overrides the electromagnetic re...
