Webb2 feb. 2024 · So, a normal force is equal to the force exerted by the object on the surface. It's formulas vary with the slope of the surface. For an object lying on a flat surface, the formula is: F N = m ⋅ g \footnotesize F_N = m ⋅ g F N = m ⋅ g. where. m \footnotesize m m is the mass of an object. g \footnotesize g g is the gravitational acceleration. Webb1 Answer. Sorted by: 1. You only need to know the difference in height between the starting point and the end point in order to know the gain in potential energy, m g h. Since you stated "assuming no energy losses", all of that energy is converted to kinetic energy 1 2 m v 2. Set the two equal - that is, put m g h = 1 2 m v 2, and solve for v.
