If you were to double the mass of a block and cart sliding down a slope, what effect would this have on displacement?

This would increase friction against the objects therefore the displacement would be halved correct?

F=?mg is the formula you would use isnt it?

Answer #1

Concept -as the mass increases, the friction force increases but the component of the gravitational force down the slope also increases. Hence the effect of increased friction force is cancelled out by the increase of component of gravitational force along the incline.

1. First consider a mass on an inclined slope of angle θ, and assume the motion is frictionless. Sketch this arrangement: 2. As the mass travels down the slope it travels a distance x parallel to the slope. The change in height of the mass is therefore xsinθ. By conserving energy, equate the change of gravitational potential energy, mgh = mgxsinθ, to the kinetic energy for the mass as it goes down the slope. Then rearrange this to find an...

Finding the Spring Constant We can describe an oscillating mass in terms of its position, velocity, and acceleration as a function of time. We can also describe the system from an energy perspective. In this experiment, you will measure the position and velocity as a function of time for an oscillating mass and spring system, and from those data, plot the kinetic and potential energies of the system. Energy is present in three forms for the mass and spring system....
