In summary, the conversation discusses the concept of work in relation to a disk rolling without slipping down an incline plane. The forces acting on the disk are identified and it is explained that only gravity does work while static friction does not. However, when looking at the definition...
2. How does mass affect the amount of work that can be done? The mass of an object does not directly affect the amount of work that can be done. However, a greater mass may require a greater force to be exerted over a longer distance in order to achieve the same displacement, res...

This is an example of energy transformation from potential energy at the highest point (the point of release) to kinetic energy at the lowest position. Since gravity is the only force doing work (tension acts perpendicular to the displacement so it does not do work), the total mechanical ener...
Make it harder:Hold a medicine ball or weights at your hips, near your center of gravity. Make it easier:Instead of elevating your working leg, just plant that foot on the ground instead. Bird Dog The Bird-dog exercise activates your glutes, lower back muscles, core and shoulders. Start ...
hard not to be an annoying gnat (or am I more of a horse fly?) circling his head. We have promised him we will wait. We will see. We should make good on that promise. We will. I just may not have much sanity left by the time we get there. I hope at least one of us does...
Because you aren’t working directly against gravity, cable exercises tend to involve more consistent muscle tension than their freeweight counterparts. For example, when you do dumbbell flies, muscle tension peaks when your arms are extended but then decreases as you bring the weights over your ...
First of all, running intervals on an incline made all of my little nagging muscle pulls and tweaks disappear. I was able to train at a high intensity without having to worry about injury. One reason for this is that sprinting on an incline decreases the impact that running has on your ...
An apple falling to the ground must be under the influence of a force, according to his second law. That force is gravity, which causes the apple to accelerate toward Earth's center. Newton reasoned that the moon might be under the influence of Earth's gravity, as well, but he had to...
For example, to lift an object, we must do work to overcome the force due to gravity and move the object upward. To lift an object that is twice as heavy, it takes twice as much work to lift it the same distance. It also takes twice as much work to lift the same object twice ...
