If the ball falls a farther distance vertically, it will have a greater kinetic energy and be going faster.

What did Galileo’s ramp experiment prove?
The inclined plane thus allowed Galileo to accurately measure acceleration with simple instruments and ultimately to prove that, in the absence of other forces such as air resistance, gravity causes all falling objects to accelerate toward Earth at the same rate.
How did the ball ACT rolling down the ramp?
With friction, there is both translational and rotational kinetic energy as the ball rolls down the ramp. When there is no slippage, the ball slides down the ramp with no rotation.
What is the force that causes the ball to go down the ramp?
In pulling the steel ball downward against the ramp, gravity causes the ball to exert a force on the ramp, which in turn exerts an equal and opposite force on the ball.
Why did Galileo choose a ramp to perform his acceleration experiment?
Galileo’s idea for slowing down the motion was to have a ball roll down a ramp rather than to fall vertically. He argued that the speed gained in rolling down a ramp of given height didn’t depend on the slope. His argument was based on an experiment with a pendulum and a nail, shown on page 171 of Two New Sciences.
What did Galileo conclude from his experiments with rolling balls?
What was the conclusion of Galileo’s 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.
How does the height of a ramp affect how far a ball rolls?
ways the experiment might end up. 1. Increasing the height of the ramp will increase the distance the ball rolls.
How does the height of a ramp affect the speed of an object?
If the ramp is steep, the force of gravity can more easily overcome the force of friction. Obviously gravity will cause an object on an incline to move down the slope faster than a flat slope.
Why does the steepness of a ramp affect speed?
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.
What type of energy is a ball rolling 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.
How do you find the acceleration of a ball rolling down a ramp?
Why does a ball roll faster down a steep slope?
The change in speed on slopes is due to gravity. If the hill is steep, then the ball will roll down the hill faster, while if you put the ball on a flatter section of land, the ball will roll at a slower rate.
How does the height of a ramp affect acceleration?
Acceleration is directly proportional to the height of the object.
How does friction affect a ball rolling down an inclined plane?
Sliding friction will quickly reduce the spin and increase the linear velocity until the ball starts to roll, at which point the friction force decreases substantially and the ball will then roll to the bottom of the incline.
Does mass affect speed down a ramp?
Weight affects speed down the ramp (the pull of gravity), but it’s the mass (and friction) that affects speed after a car leaves the ramp. Heavier cars have more momentum, so they travel further, given the same amount of friction.
How the angle of slope affect the time taken for a ball to roll down the slope?
When the angle increases the time taken for the ball to roll down the ramp decreases.
What is the conclusion of inclined plane experiment?
Forces and Laws of Motion Describe Galileo’s experiment with inclined planes and state the conclusion. Galileo deduced that objects move with constant speed when no force acts on them, by observing the motion of objects on inclined planes.
What did Galileo discover using balls and inclined planes?
As the ball rolled down the plane, Galileo found that it traveled down the ramp at a uniformly increasing speed. The relationship between distance traveled and time was not linear.
What did Galileo discover when he dropped two cannon balls of different weights from the Leaning Tower of Pisa?
What did Galileo discover when he dropped two cannon balls of different weights from the Leaning Tower of Pisa? The time for both of the balls to reach the ground was the same. Which scientist first discovered that white light is a mixture of a rainbow spectrum of light rays?
When a ball rolls on the floor it will eventually stop what force causes the ball to stop?
The friction force acts in the opposite direction to the motion of the ball, slowing it and eventually stopping it.
What happened to the value of the acceleration of the rolling ball?
As Galileo changed the angle of inclination of the planes he used, what happened to the value of the acceleration of the rolling ball? The acceleration of the rolling ball increased as the steepness of the plane was increased.
Does height increase velocity?
Yes, height does increase the final velocity of a falling object.
How did changing the height of the ramp affect the amount of work done?
As ramp height increases, applied force also increases. How does increasing the height of the ramp affect work (when length and weight are constant)? As the ramp height increases, work also increases.
Will a car racing down a ramp travel a shorter or greater distance if you raise the ramp’s height?
Conclusion. From my preliminary results I have found that the height of the ramp does affect the speed of the car – the higher the ramp is the faster the car will travel.
Why does acceleration increase with height?
Important Conclusions on Acceleration due to Gravity : For an object placed at a height h, the acceleration due to gravity is less as compared to that placed on the surface. As depth increases, the value of acceleration due to gravity (g) falls. The value of g is more at poles and less at the equator.
