... An object sliding down an incline has three forces acting on it: the normal force, gravity, and the frictional force. • The normal force is always perpendicular to the surface. • The friction force is parallel to it. • The gravitational force points down. If the object is at rest, the forces are the ...

... Newton’s second law answers the question of what happens to an object that has a nonzero resultant force acting on it. Newton’s second law states that; if a net force acts on a body, the body will accelerate. The acceleration of an object is directly proportional to the resultant force acting on it ...

... 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 ...

... Forces of rolling If a wheel rolls smoothly, there is no sliding at the contact point so there is no friction. However, if there is an external force that produces an acceleration, there will be an angular acceleration, . The acceleration will make the wheel want to slide at the contact point. Then ...
