A student draws an energy diagram to explain why the temperature changes between a when a hot flask is placed inside of a cold beaker. What is wrong with the energy diagram below?

If a sphere and a cure have the same mass and are propelled up a ramp with the same force, which would travel father up the ramp? explain.

What is the scientific definition of energy that relates to work

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?
