State Newton's Law of Gravitation
A force of attraction between 2 point masses which is inversely proportional to the square of the distance between them and proportional to the product of the masses.
1 of 5
State, in words, how the force acting on a body is related to the change in momentum of the body
Force = rate of change of momentum
2 of 5
Define the electric potential at a point in an electric field
Work done per unit charge on a small positive charge in moving from infinity to the point.
3 of 5
Define the gravitational potential at a point in a gravitational field
Work done per unit mass on a small test mass in moving from infinity to the point
4 of 5
State Coulomb's Law
Force between two point charges is proportional to the product of the charges and inversely proportional to the square of the distance between them.
