# What happens when you roll a ball down a ramp?

## What happens when you roll a ball down a ramp?

When you lift an object up off the ground, it has potential energy due to gravity. 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.

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

1. 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 force causes a ball to roll down a ramp?**

Gravity

Consider this hollow ball rolling down a ramp: Gravity exerts a force F = mg on the center of the ball, directed vertically downwards. Now, if the ball is rolling without slipping, that means that the portion of the ball which touches the ramp is — for a moment — motionless.

### Why does a ball accelerate as it rolls down a hill?

The change in speed on slopes is due to gravity. When going downhill, objects will accelerate (go faster), and when going uphill they will decelerate (slow down). On a flat surface, assuming that there is little friction, they will then maintain a constant speed.

**What factors affect the distance the ball travels?**

The distance a baseball travels depends on two primary factors: the angle at which the ball leaves the bat, and how fast the ball is hit. The speed of the ball depends on both the speed of the pitch and the speed of the bat.

**What is the dependent variable of a ball rolling down a ramp?**

The dependent variable was the time; so when I let the ball roll down the textbook(ramp) I timed it by the stopwatch and stopped it when it landed on the point I wanted, the dependent variable was the angle of the textbook; using the protractor I measured the angle so the ramp would be the same for all the times I …

## How does the height of a ramp affect acceleration?

Acceleration is directly proportional to the height of the object. It is important to consider to what extent the results show this relationship.

**What are two forces that would cause a ball to roll down a hill?**

The diagram at the right depicts the two forces acting upon a crate that is positioned on an inclined plane (assumed to be friction-free). As shown in the diagram, there are always at least two forces acting upon any object that is positioned on an inclined plane – the force of gravity and the normal force.

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

Galileo argues that a similar pattern will be observed if a ball rolls down a ramp which is smoothly connected to another steeper upward ramp, that is, the ball will roll up the second ramp to a level essentially equal to the level it started at, even though the two ramps have different slopes.

### How to measure time to roll distance down a ramp?

In this part the distance d down the ramp is the variable while the angle of slope is constant. 1. Set up the ramp with h= 0.10 m above the table, (as shown in Figure 1.) 2. Starting with the cylinder at rest, use the stopwatch to measure the time to roll distance d = 1.0 meter down the ramp.

**What was the conclusion of the rolling ball experiments?**

The conclusion of the rolling ball experiments was that the velocity of a falling object is proportional to the time of its fall. Galileo proved that this means that the distance traveled by the ball was proportional to the square of time.

**Why did Galileo use a ramp in his experiment?**

Galileo designed experiments to study accelerated motion using the inclined plane. His reasoning suggested that objects rolling down a ramp behaved similarly to objects in freefall so that he could understand freefall by studying ramps. This experiment is designed to reproduce a portion of Galileo’s experiments.
