Two blocks of mass m1 and m2 (m1 > m2) slide on a frictionless floor and have the same kinetic energy when they hit a long rough stretch (μ > 0), which slows them down to a stop. Which one goes farther?

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

Why is the energy that results from a roller coaster's position at the top of a hill referred to as potential energy?

Ahuge (essentially infinite) horizontal nonconducting sheet 10.0 cm thick has charge uniformly spread over both faces. the upper face carries +95.0 nc/m2 while the lower face carries -25.0 nc/ m2. what is the magnitude of the electric field at a point within the sheet 2.00 cm below the upper face? (ε0 = 8.85 × 10-12 c2/n · m2)
