Question

A particle is acted upon by a force of constant magnitude, which is always perpendicular to the velocity of the particle, the motion of the particle takes place in a plane. It follows that

The potential energy between two atoms in a molecule is given by U(x) = a/x¹² − b/x⁶; where a and b are positive constants and x is the distance between the atoms. The atom is in stable equilibrium when

When a conservative force does positive work on a body, then what would happen to potential energy the body?

A ball of mass 50 g is thrown vertically upwards with an initial velocity of 20 m s⁻¹. Calculate the energy dissipated if it has potential energy of 6 J at the maximum height.(g =10 m s⁻²)
