How the energy of a marble is transformed as it rolls down a ramp?
As the marble rolls down the hill its potential energy is converted to kinetic energy (its height decreases, but its velocity increases). When the marble goes back up the loop its height increases again and its velocity decreases, changing kinetic energy into potential energy.
How is energy conserved when a ball rolls down a hill?
When a football rolls down a hill, the potential energy of the ball turns into kinetic energy at the bottom. However, if you carry the ball down and stand with it at the bottom, the ball has no kinetic energy.
What happened to the potential energy of the marble as it rolled down the ramp and hit the cup?
This means that the marble has the potential to roll down and knock the cup. So, YOU gave the marble potential energy by picking it up and holding it at the top of the ramp. When the marble hits the cup, the marble transfers energy to the cup which then moves.
How is energy conserved in a falling object?
As an object falls from rest, its gravitational potential energy is converted to kinetic energy. Conservation of energy as a tool permits the calculation of the velocity just before it hits the surface. K.E. = J, which is of course equal to its initial potential energy.
Is energy conserved during rolling?
In the absence of any nonconservative forces that would take energy out of the system in the form of heat, the total energy of a rolling object without slipping is conserved and is constant throughout the motion.
Is energy conserved in rolling?
Mechanical energy is conserved in rolling motion even when friction is present.
What happens when you roll a marble down a ramp?
Explanation When the marble is at the top of the ramp, it has potential energy because gravity will pull it down. This is called gravitational potential energy. When the marble is released, it begins to move, and the potential energy changes into kinetic energy. Objects in motion are said to have kinetic energy.
What happens when a marble rolls down an inclined plane?
He observed that when a marble rolls down an inclined plane, its velocity increases [Fig. 1(a)]. When marble falls under the unbalanced force of gravity as it rolls down and attains a definite velocity by the time it reaches the bottom.
How does the law of conservation of energy apply to a marble rolling down ramps made of different materials?
How does a marble that rolls from the top to the bottom of a ramp demonstrate the law of conservation of energy? As the marble rolls down the ramp its potential energy is converted into kinetic energy so that the total mechanical energy of the marble remains the same.
How do you know if energy is conserved?
If only internal forces are doing work (no work done by external forces), then there is no change in the total amount of mechanical energy. The total mechanical energy is said to be conserved.
Is energy conserved when a ball is dropped?
What happens to energy when objects collide, for instance if you drop a ball? Energy cannot be created or destroyed, but can be transformed. If a ball drops, energy is transferred and transformed, in sound for instance, but the total amount of energy remains the same.
What happens to the energy while the ball is falling?
As the ball falls towards the ground, its gravitational potential energy is transformed into kinetic energy. The kinetic energy of the ball will continue increasing as the ball gains momentum, until it finally collides with a surface.
Is energy conserved when a ball is dropped?
What happens to energy when objects collide, for instance if you drop a ball? Energy cannot be created or destroyed, but can be transformed. If a ball drops, energy is transferred and transformed, in sound for instance, but the total amount of energy remains the same.
How is energy conserved in the ball?
Initially, the ball has a lot of kinetic energy, because you've given it a pretty large upward velocity. In this case, the total energy is conserved because it doesn't change. However, as the ball moves upward, it slows down as its initial kinetic energy is transformed into potential energy.
What happens when a ball rolls down a hill?
When a rolling object, such as a ball or something on wheels, goes down a hill it will speed up. When it goes up a hill it will slow down. On a flat surface, it will keep going at the same speed. The change in speed on slopes is due to gravity.
What happens to a ball as it rolls down a hill?
The gravitational potential energy is transformed into motion energy as the ball rolls down the hill. The gravitational potential energy decreases and the motion energy increases. As soon as the ball starts moving it no longer has gravitational potential energy; it has only motion energy.

What happens to the final velocity of marble after rolling down the ramp?
In other words, as you increase the starting height of the marble, the final velocity of the marble after rolling down the ramp increases quadratically.
What is the relationship between the final velocity and the starting height of a marble?
1) The square of the final velocity of a marble after rolling down a ramp has a positive proportional relationship with the starting height of the marble. Also, the final velocity of a marble after rolling down a ramp has a positive proportional relationship with the square root of the starting height of the marble.
What is systematic error?
Some sources of error are systematic, which means that they will skew every single point of data in your collected data in the same way. In this experiment, the placement of the Labquest photogate set a certain distance for the marble to slow down from friction, reducing the final velocity of every single data point. Systematic errors reduce the accuracy of your experiment: how close you were to the truth.
What is the trend line in Figure 2?
Figure 2: Scatter plot graph of final velocity compared to the square root of the starting height of the marble. The trend line is linear, with an equation of v = 4.97h 1/2 - 0.23.
What are the sources of error in a marble experiment?
Other sources of error are random, which means that they will randomly increase or decrease the value of each point by a different amount every time. In this experiment, the initial placement of the marble at the top of the ramp increased or decreased the initial velocity and initial height of the marble for each trial, which in turn affected the final velocity of the marble. Random errors reduce the precision of your experiment: how consistent and detailed your results were.
