This can be mathematically written as,Key points: Potential energy is energy that has the potential to become another form of energy. The force applied to the object is an external force, from outside the system. Either side equals the total mechanical energy. So, when you lift the body, you are increasing the potential energy of the system (earth-object) & not increase the internal energy of the object. We will use y = y 0 + v 0 t + 1 2 at 2 because it includes only one unknown, y (or y 1, here), which is the value we want to find. velocity. This force is what keeps your body on the ground. If the mass or speed of an object increases, so does its kinetic energy, if it decreases its kinetic energy would decrease as well. A centripetal force is a net force that acts on an object to keep it moving along a circular path. 6. O I ts mass decreases. For example, because Earth is so massive, it attracts you. C. If the x-axis of a coordinate system is chosen parallel to the spring and the equilibrium position of the free end of the spring is at x = 0, thenNow as a force of constant power, I can clearly see that as the force increases, the velocity of the body on which the force is applied would decrease. newton's second law in the form F=ma. disease D. The force F the spring exerts on the object is in a direction opposite to the displacement of the free end. The gravitational field exerts a force on an object, and this force determines the object’s potential energy. A conservative force is one, like the gravitational force, for which work done by or against it depends only on the starting and ending points of a motion and not on the path taken. F B =wfl, F B = w fl, where F B F B is the buoyant force and wfl w fl is the weight of the fluid displaced by the object. As the normal force increases, so does the force of static friction. 8 m/s, but that is velocity and not acceleration. as well as the acceleration due to gravity. So does its acceleration.
