What happened to the potential energy of the marbles as it rolled down the ramp and hit the cup?

What happened to the potential energy of the marbles as it rolled down the ramp and hit the cup?

When the marble hits the cup at the bottom of the ramp, energy is transferred from the marble to the cup causing the cup to move. As a result, when the marble is released and the gravitational potential energy is transformed (primarily) to kinetic energy, the marbles released from higher up can move the cup farther.

Does the marble make it through the loop?

You should have found that the marble had to start higher than the top of the loop in order to make it the whole way through the loop. This happens because some energy is always lost to friction as the marble rolls down the track.

What slowed the marble down?

To slow down the marble, a force has to be applied in the opposite direction from the marble’s motion. Applying a force over a longer period of time results in a greater change in velocity. When we blew harder or more team members blew through their straws, the marble moved faster.

What happens after a rolling marble hits the stack of marbles?

It depends on an object’s mass and how fast it is moving. In a collision, according to Newton’s third law of motion, momentum is conserved. That means what goes in, has to come out. That is why when you hit one marble into the stack, only one moves out.

What made the marble roll faster?

When an object is in free fall, gravity increases its velocity by 9.8 m/s with every passing second. Specifically, the distance between the one- and two-second marks should have been greater than the distance between the starting line and the one-second marks, showing that the marble moved faster the longer it rolled.

Why does a marble roll down a ramp?

Gravity and potential energy are related. It is gravity that is pulling the ball down the ramp. So that marble teetering at the top of the ramp has the potential energy of gravity — which is the force that will pull it down the ramp with no effort from you (once you’ve tipped it onto the ramp).

What can change a marbles speed?

Concepts: -Objects move when pushed or pulled. -Objects will change speed and direction when in contact with another object. -Force (how hard the marble is pushed) will affect how fast the marble moves (speed).

What’s the average speed of a roller coaster?

With the notable exception of Top Thrill Dragster (Cedar Point)—which squeezed into the hallowed ten with a combination of top specs and rider votes—most of our top picks have good-but-not-extreme stats, with an average top speed of 81 mph and an average max height of 237 feet.

How do we find speed?

The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.

What happens when two marbles collide?

When the marbles collide, Newton’s third law tells us that the force each exerts on the other is equal in strength and opposite in direction. Because the masses are the same, Newton’s second law tells us that the acceleration of the balls during the collision will also be equal and opposite.

Why does marble always roll down the track?

You should have found that the marble had to start higher than the top of the loop in order to make it the whole way through the loop. This happens because some energy is always lost to friction as the marble rolls down the track.

Where does the energy go on a marble roller coaster?

If you watch the marble closely, you might be able to see that it is going the fastest right at the bottom of the hill before it enters the loop. As the marble rolls down the hill its potential energy is converted to kinetic energy (its height decreases, but its velocity increases).

When does the marble have its maximum potential energy?

The marble has its maximum gravitational potential energy when it is at the starting point: the highest point on the roller coaster. How much of this potential energy is converted to the marble’s kinetic energy?
