Question

What happens to the speed and the direction of motion of a ball rolling down are inclined plane?

Answer 1

Rolling motion is the rotation and translation combination. If a ball rolls, the ball is in the motion of rotation on the surface of the ground. Simultaneously, the ball moves from one point to another so there is a motion of translation.

• The angular velocity is the cause of the impending rotational motion whenever a rigid body is supplied with a force producing torque. This is why static friction is opposed and the direction of friction is moving.
• When there is an increase the steepness of the slope, there will be an increase the speed of a ball rolling down the ramp. This is observed as, the force of gravity points straight down, but a ball rolling down a ramp does not go straight down, it follows the ramp.
