Since the two forces pushing you in opposite directions are nearly equal, your body feels very light. As in the sharp descent, you are almost weightless for the brief moment when you are at the top of the loop. As you come out of the loop and level out, you become heavy again. In a loop-the-loop, the intensity of the acceleration force is determined by two factors: the speed of the train and the angle of the turn.
Investigating the Factors that Affect the Period of One Swing of a Pendulum Aim: To investigate the factors which affect the period of one swing (oscillation) of a simple pendulum. The factors I will use are length of the string, and angle that the bob is released from. Hypothesis: 1. Length of string I think that the length of the string directly affects the period of one oscillation. The mathematical formula used to describe the period of the pendulum is: T= 2 pâˆštex2html_wrap_inline105/g T is the period (time for one swing - seconds) tex2html_wrap_inline105 is the length of the pendulum (metres) g is the acceleration dues to gravity.
Research and Background A pendulum is an object hanging from a fixed point with a mass that swings back and forth under the influence of gravity. Sometimes this mass is called a bob, as it bobs up and down as it swings side to side. Pendulums are acted upon by three main forces: gravity, tension, and air resistance. While gravity always pulls down on the bob, tension pulls upward towards the pivot point for the string on the rod, or where the string pivots. However, both the amount and the direction of the pendulum’s tension changes as it swings.
Introduction The purpose of this experiment was to understand how different variables can affect the period of oscillation of a pendulum. Aim: To determine the acceleration due to gravity, by varying the length of an inelastic string and measuring its corresponding period of time for each experiment. Apparatus used Retort stand Clamp Stop watch Pendulum bob Ruler Counter weight Rigid support Inelastic string Vernier caliper Theory According to Crundell (2001, p231) Simple harmonic motion is defined as the motion of a particle about a fixed point such that its acceleration a is proportional to its displacement x from a fixed point, and is directed towards the fixed point. There are many ways in which we can observe the special kind of oscillations
Also, the hook was used for attachment of the hanger with the slotted weight. Theory: In static equilibrium, force of a spring is proportional to and directed opposite to the elongation. This is represented by Hooke?s Law where the restoring force is equal to elongation distance from equilibrium multiplied by the constant force of the body. From that equation, the experimenter will know how much force is needed to be applied to the spring in order to stretch it a particular distance. The experiment also deals with dynamic oscillation that deals with the period of oscillation, which is independent of displacement.
I am going to measure the acceleration of the trolley in m/s as the mass on the pulley changes. As the masses will be acted on by gravity they will extent a force on the trolley and I will use g= 10N/K to work out the force for each mass. Prediction: I predict that the larger the force in grams acting on the trolley the larger the acceleration of the trolley. I think this because by using the equation F=M*A. This shows me that force is proportional to acceleration.
Pendulum Investigation Plan Aim To investigate how the length of a simple pendulum will affect the time for a full swing. Variables Length The length of the pendulum has a large effect on the time for a complete swing. As the pendulum gets longer the time increases. As the pendulum gets shorter the time decreases. Air resistance A big and light pendulum bobble would be affected by a major amount of air resistance.
Simple Pendulum Introduction The purpose of this lab was to determine the motion and energy associated with a pendulum. Not only did we physically observe the differing motions of the pendulum, we also determined which types of energy were associated with the pendulum at a specific moment in time (potential, gravitational, and kinetic). The pendulum contained potential energy as soon as you let go of it and as soon as it reached maximum deflection. The pendulum contained gravitational energy when it was displaced from its resting point. The pendulum contained kinetic energy while it was moving from side to side.
The gravity vector is always the sum of these two vectors. Image[5 stages] As the pendulum swings, both of the component vectors change direction. Fgrav-tangent is always tangent to the arc that is the motion of the pendulum, and Fgrav-perp is always perpendicular to it. Fgrav-tangent acts as the restoring force. As the bob moves to one side of the equilibrium point, Fgrav-tangent points in the opposite direction, slowing the bob until it reverses its direction back to the equilibrium.
Studying a Simple Harmonic Oscillator Objective --------- The simple harmonic motion of a pendulum can be studied by attaching a ticker-tape to a pendulum bob and analyzing the dots marked on the tape. Theory ------ In this experiment, a string was used to suspend a 0.5 kg mass.

Therefore, we can find out more on simple harmonic motion by analyzing the ticker-tape we obtained after the experiment. Apparatus --------- 1.
