WebThe work we do on the rock also equals the rock’s gain in gravitational potential energy, PEe. W = P E e = m g d. Kinetic energy depends on the mass of an object and its velocity, v. K E = 1 2 m v 2. When we drop the rock the force of gravity causes the rock to fall, giving the rock kinetic energy. WebNo, because we know now that during the horizontal motion, gravity's not doing any work. So this displacement doesn't come into the picture. During the vertical motion gravity is doing work. Gravity is pulling and make it displace, so this matters. Again, during the horizontal motion, that displacement doesn't matter.
