ground, so it accelerates. If the track tilts up, gravity applies a downward force on the back of the

4. Connect the Newton Scale to the cart and then drag the cart up the ramp, across the 30cm difference at a steady rate.

4. Place the mass on the bottom of a ramp and attach the loop of string to the

If the resultant net force acting on the cart increases and total mass remains constant, than the acceleration will increase proportionally because Newton’s second law of motion states that acceleration is equal to the net force over the mass of the system; this demonstrates a directly proportional relationship between acceleration and net force because when acceleration increases, so does net force (Newton’s second law).

The aim of the experiment is to examine how the acceleration of the car differs when the angle of inclination of the ramp is amplified and to record and analyse findings.

We experienced the effects of pushes and pulls in Activity 2 when we played around with the carts on the track. We noticed in experiment #1 that it doesn’t matter if you push or pull the cart to get it moving. We were also able to identify that when we gave the cart a second push it would speed up. In Activity 3 we messed around with the friction pads on the carts to show that the cart will slow down when there is a force acting in the opposite direction. When we tapped the cart the other way, there was also either a change in directions or a decrease in speed.

Potential and Kinetic energy plays a big role in the roller coaster´s energy to go up and down hills during the ride. Let me start it off by explaining what potential and kinetic energy is, Potential energy is stored energy that is kept for when it needs to be used. Kinetic energy is energy in motion, for example when a roller coaster is going up the initial hill the train is using potential energy but as soon as the chains let go at the top of the hill the coaster is using kinetic energy because the train is in motion. These energies play a part in this specific place because when a roller coaster is using potential energy it is saving and storing energy and not using anything because the train isn't in motion. On the other hand kinetic energy

These 2 forces are potential and kinetic energy. The potential energy is what is being made when it is going up the hills because gravity could take over and pull it down at any moment and kinetic energy is the energy that is created when going down the hill. The potential energy flows into kinetic when the rollercoaster begins to fall down the hill then goes back up and so on. These 2 things are in a cycle until the end of the coaster because when one is not in use the other is.

Then as the coaster begins its decent down the first hill, the energy is converted back into kinetic energy as the train is pulled toward the Earth by gravity. Gravity is the traditional source of power for roller coasters that accelerates the train as it goes on its hilly, twisty journey.3 Gravity is a unit of acceleration, that is always present, that causes free-falling objects on Earth to change their speed at a rate of approximately 10 m/s (32ft/s) every second.1 So, as the train goes down the hills of the track it has a positive acceleration giving it the necessary potential energy to “climb” the next hill, make a turn, or travel through a loop.

4. Experiment 2: Cart loaded with magnets travelling parallel to conductor. Experiment 2 will serve to provide an insight into the nature of the braking force, such as whether it varies with time or is constant throughout. It will serve to also answer the question, how does initial velocity affect acceleration? My hypothesis is that as the cart is moved farther and farther away from the aluminum strip, it will reach a higher peak velocity, and the magnitude of the braking effect will also increase as a

Diamond Fall cart will come out in a triangular that holds up to 30 people in one cart there will be two carts going out at the same time so, 60 people in all will be riding the ride. When you leave, you will have an Inertia jerk when you start to go off. As the cart goes down the hill in the beginning you will have up the steep hill there will be Potential energy.Has you go over the hill there will be an Inertia Jerk and Terminal Velocity and then you are going to hold for a couple seconds,and then you go free fall down the hill.Then,you are going to go off the tracks and go through a half pipe and you’re going to be weightless..Also,passengers in the cart will be going upside down loop,which is centripetal acceleration and speed.The car gonna go up a hill watch a video on how the workers found the diamonds,which will be 15 seconds long.Then,you’re going to be going backwards till the you reach the end of the big hill and then you are going to switch tracks and go underground.As you are going underground the highest air pressure will be there as the cart is going down hill.Next,you are going to be in tight turns,centripetal force.Also, going off the tracks again,it’s like a tube but, it’s going to have different

The car is pulled to the top of the first hill using chains and an assortment of gears to pull the car to the summit of the roller coaster. Then it turns the potential energy into kinetic energy as the car excels down the hill at high speeds. After this the kinetic and potential energy rock back and forth throughout the thrilling ride. At the beginning of a roller coaster a winch pulls the car to the top of the ride. This energy does not disappear but is instead saved up by the car the higher it goes and uses this, what we call potential energy, to parachute down the summit. As it does so it is turning that potential energy into kinetic energy that is at this point being used for the coaster. Potential energy is energy that can be stored or

The lift motor exerts energy to the roller coaster, giving it gravitational potential energy at the top of the hill. This energy will then be converted into kinetic energy when the coaster

Figure 2: Sketch of Setup As shown in figure 2, the setup consisted of stacking the ramp on top of textbooks, the motion sensor at the top, and the cart about 15 cm away from it. The next step was to measure the acceleration of the cart without any weights. After three trials, the data recorded by the motion sensor was averaged. The slope of the line indicated the velocity. The previous steps were repeated, with a 100g weight increasing after every three trials.

The bigger the mass of the toy car is, the more frictions it will create while rolling down the ramp and therefore the more unbalanced force and speed bumps it will face and slowing it down. So an object with smaller mass will travel much faster than an object with a bigger mass on the same angled ramp.The reason for is hypothesis is that the bigger the mass of an object is, the more contact it will have on the surface of the ramp, therefore creating more frictions. When two solid surfaces (one moving and one still or both moving) make contact with each other and is created frictions. The more friction there is, the slower an object will travel and the quicker an object will
