Product Instructions: Inclined Plane
... For a normal balance, the two masses would need to be the same in order for the system to be in equilibrium. However, only a component of the weight of 1 is acting to pull it down the incline, so the mass of 2 only need be equal and opposite to the component of 1 acting along the incline. ...

Concept Questions
... Answer 3. Energy is not conserved because there are energy losses due to kinetic friction. Angular momentum about the center of mass is not constant because the friction exerts a torque about the center of mass. Angular momentum about a fixed point on the ground is constant because the sum of the to ...

... In which direction does friction act? Friction always acts in the opposite direction to which an object is moving. An object will only start to move if the forces applied to it are greater than any frictional forces. What is the direction of friction acting on each moving ball? ...
