Acceleration on an Inclined Plane
What is the acceleration of an object down an inclined plane? What do the motion graphs of an object down an inclined plane look like? Galileo Galilei...
Static Equilibrium
Objects remain at rest only when the net force and the net torque are zero. The converse is also true: if an object remains at rest, then you know the...
Work and the Force Versus Distance Graph
How are force, distance, and work related graphically? To lift a mass, you must do work on it against...
Inclined Plane and the Conservation of Energy
What law governs the energy transformations of motion on an inclined plane? If you have ever skied...
Work and Energy
How is the work done on a system related to its change in energy? How is the efficiency of a system calculated? Have you ever pulled a swing back and let...
Springs and the Conservation of Energy
Can energy conservation be used to predict the behavior of a system? A system consisting of a cart...
Work Done by Friction
The work done by friction reduces the amount of energy available for transformation into other forms.
Crash Barrier
Construct a crash barrier designed to minimize the impact force experienced by a cart in a collision.
Conservation of Momentum
The law of conservation of momentum is a powerful generalization of Newton’s third law. For an isolated system, the total momentum of all the objects...
Inelastic Collisions
In this investigation you will explore how the total kinetic energy and momentum of a closed system involving two carts is affected by a perfectly inelastic...
