## What happens when a ball rolls down a ramp?

So when you roll a ball down a ramp, it has the most potential energy when it is at the top, and this potential energy is converted to both translational and rotational kinetic energy as it rolls down.

**Is a ball going down a ramp accelerating?**

Therefore, only the component of the gravitational force which points along the direction of the ball’s motion can accelerate the ball. The other component pushes the ball into the ramp, and the ramp pushes back, so there is no acceleration of the ball into the ramp.

**How does gravity affect a ball rolling down a ramp?**

Gravity accelerates objects down ramps — but not the full force of gravity; only the component of gravity acting along the ramp accelerates the object.

### What affects how far a ball rolls down a ramp?

Increasing the height of the ramp will increase the distance the ball rolls. 2. Increasing the height of the ramp will decrease the distance the ball rolls.

**What will happen to the acceleration of a ball as it rolls down an inclined plane?**

The acceleration of a ball down an inclined plane could be analysed as a first approximation by ignoring the friction force. In that case, the ball would simply slide down the incline without rotat- ing, with acceleration a = g sin θ, since there is then no torque on the ball to rotate it.

**What happens to the motion of the ball as it rolls up on an inclined plane?**

As the angle increases, the component of force parallel to the incline increases and the component of force perpendicular to the incline decreases. It is the parallel component of the weight vector that causes the acceleration. Thus, accelerations are greater at greater angles of incline.

#### How does the height of a ramp affect the speed of a ball?

Variables: The height of the ramp will change the speed and distance the ball rolls because when the ramp is higher, the ball will be higher. The higher the ball is the more gravitational potential energy it has; therefore more energy will be transferred to kinetic energy.
