To investigate how the angle of a slope affects the acceleration of a marble.

Introduction

Motion Down a Slope

Aim:

To investigate how the angle of a slope affects the acceleration of a marble.

Introduction:

        As bodies freely roll down a slope they accelerate. Various factors may affect the acceleration.

Variables:

There are a number of things that affect the acceleration of the marble:

  • Angle/Gradient of slope. Changing the angle of the slope would affect the acceleration of the squash ball as it changes the energy the marble starts with as steeper angles raise the slope start higher so the marble would have more potential energy.
  • Mass of marble.Changing the mass of the marble would affect the acceleration because it means it has more energy pulling it downwards and so would accelerate faster.
  • Surface. Changing the surface may change the amount of friction between the slope and the marble. This would affect the amount of energy absorbed. If there was more friction then more energy is absorbed so the marble has less pushing it along and so accelerates slower.
  • Gravity. A change in the gravity would change the amount of energy pulling down the marble and so change the amount of energy pushing it along and so change the acceleration of the marble.
  • Aerodynamics. A change in the aerodynamics would create a change in the air friction. This would change the amount of energy absorbed and so change the amount of energy left pushing it along changing the acceleration.

Conclusion

        My results suggest that the theoretical data was correct, as mine where only slower due to friction, and they support the conclusion. Further investigation could be done to help support this. For example, using a perfectly round ball such as a metal ball bearing, and a smooth metal slope. This would remove some of the friction and get closer results to the theoretical set. Also for further work the marble could be rolled down different texture slopes to investigate the effects of varying amounts of friction. This would provide additional information, which would help identify exactly how much friction does affect the results, compared to the theoretical set.

To extend the investigation you could do the same experiment but keep the slope at the same angle and change the mass of the ball. This would investigate how the mass effects the acceleration.

  2. Squash Ball and Temperature Investigation

    Results To ensure that a wide range of results would be taken so that a good conclusion can be formed from them, we chose to take 15 different readings of temperatures and tested the squash ball at each temperature five times.

  1. Investigation into Friction.

    From the results in the table, we can say that there are no readings that are very far away any other reading, and this indicates that this part of the experiment was also done accurately, and reliably. Conclusions from the graph Graph 1 shows the readings on the force meter (F)

  2. Investigating the amazingness of theBouncing Ball!

    For that work to be done energy must be expended (in the case of a squash/rubber ball, it bounced onto the floor). Some of this energy is dissipated (as heat, etc), but some is stored in the defromed material and is released when the material relaxes.

    Incidentally, "ball bounce resilience" is equal to the "coefficient of restitution" squared, and then expressed as a percentage. For example, if a ball is dropped from 3 meters, hits the ground, and bounces up 1 meter, the BBR is 33.3%.

    A bigger ball could catch on the crocodile clips. I predict that the closer the angle is to 90�, the faster it will accelerate. I am able to make my prediction by using my own knowledge and information from textbooks. When objects fall naturally, they fall at a 90� angle.

  1. Determining the Acceleration Due to Gravity

    At its highest point (furthest away from equilibrium) it has no kinetic energy, but full potential energy. This potential energy is equal to the energy put into the system (the energy used to start the swing). At the equilibrium position all the energy is kinetic and so the mass is moving at the greatest velocity.

  2. Friction and its issues.

    That's why it is easily to slide on ice. Without friction life would be very difficult. None of the above we can do without friction. According to the first law of Newton, if there is no force on something, if still, it will say still, and if moving, it will continue moving in a straight line with a steady speed.
