Acceleration Due to Gravity Have you ever wondered why items always speed up when they are falling? Well it all has to do with acceleration due to gravity. Acceleration is the rate at which an object changes its velocity. Acceleration can be calculated by finding the change in velocity and dividing it over the time. The equation is: a= ∆v∆t (“Acceleration”) Acceleration is also a vector because it has a direction. The units of acceleration are typically m/s2. Gravity is the force that attracts

Determination of the Acceleration Due to Gravity By A Good Student Abstract The acceleration due to gravity‚ g‚ was determined by dropping a metal bearing and measuring the free-fall time with a pendulum of known period. The measured value is 9.706 m/s2 with a standard deviation of 0.0317‚ which does not fall within the range of known terrestrial values. Centrifugal forces and altitude variations cannot account for the discrepancy. The calculation is very sensitive to the measured drop

Using a simple pendulum to find the acceleration due to gravity/g Task 1 Aim: To find the acceleration due to gravity/g Objective: To find the relationship between the length of simple pendulum and the period oscillation Hypothesis: The longer the length of the simple pendulum‚ the longer the period of oscillation will take. Variables: a) Independent- the length of the pendulum; b) Dependent- the time it takes for 20 oscillations; c) Control - the mass of pendulum. Task 2 References

The purpose of this experiment is to measure acceleration on a freely falling object assuming the only force acting on the object is gravitational force. Theory All dense objects in free fall have the same acceleration‚ which is known as the acceleration due to gravity. The value of acceleration due to gravity is approximately 9.80 m/s2. In this experiment‚ a vertical stand with an electromagnet at the top for holding and then releasing of the falling body‚ called the plummet. The plummet

air-cart is pulled by the known mass when hung over a pulley. A spark timer will mark the motion at a frequency of 10 Hz (10 dots/s) on a strip of paper called ticker tape. The air-track will supply air through the apparatus to simulate a frictionless environment‚ enabling the system of masses to move without an applied force or a frictional force. This experiment will measure the motion of an air cart attached to a known mass by string moving on an air track using kinematics and dynamics concepts

It can also be described as the rate of change in velocity. Acceleration is represented by the formula: . In this experiment we look at a specific type of acceleration‚ Free-Fall. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. There are two important
