amplitude of the pendulum is quite small‚ then the time period of the pendulum can be found according to the following equation: ‚ where l is the length of the arm of the pendulum (between the pivot and the centre of mass of the bob) and g is the acceleration due to gravity (on earth ñln9.81). For the spring‚ a similar equation can be derived. For any spring‚ ‚ where m is the mass of the bob on the spring and k is hookes constant. Hookes constant is the constant of proportionality of force against

purpose of this lab was to prove Newton’s 2nd Law; which states accelerate equals force divided by mass (a=F/m). During this lab we were trying to find out the relationship between acceleration‚ force‚ and mass by using a air track‚ glider with picket fence‚ and photogates. Before I did the lab‚ I had already knew that acceleration‚ force‚ and mass were related. I just didn’t know how they were related. When recording the results of this lab we had to record the applied force in Newton’s. Newtons’s is a

to show that the acceleration is proportional to the force causing the motion. Theory Newton’s second law of motion states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the total mass. a = net force/ total mass If an object is acted on by a net force ‚ it will experience an acceleration that is equal to the net force divided by the mass. Because the net force is a vector‚ the acceleration is also a vector‚

Reid Purpose: To determine both qualitative and quantitative properties of the motion of a cart on an inclined plane on position vs. time‚ velocity vs. time and acceleration vs. time graphs. Question: Which properties of the cart’s motion can be determined from examining each of the three graphs? Hypothesis: The predictions on the type of motion demonstrated by the cart-qualitatively- are shown below.

Lab 3: Newton’s Second Law: The Atwood Machine Introduction: In the study of physics a lot of the basics were put in place by Isaac Newton. Out of the 3 laws of motion he had declared the second law states that force equals mass times acceleration (F=ma). The Atwood machine is a machine that has a pulley in the air and a string running through the pulley‚ some kind of mass is suspended by each end of the string. When the suspended masses are unequal‚ the system will accelerate towards the direction

We will assume that Up is the positive direction and Down is the negative direction. Case 1: No acceleration of elevator If the acceleration of the elevator is zero‚ then there are two possible scenarios; the elevator can be at rest (stationary‚ zero velocity) or moving with a constant speed (no acceleration if velocity does not change).

this Motion Lab was to find the acceleration of a steel marble going down a straight track six different times to figure out how an object’s mass affects acceleration. It doesn’t due to Newton’s second law of motion. There were six different accelerations for each trial and they are: 7.88 m/s squared‚ 6.78 m/s squared‚ 6.07 m/s squared‚ 5.57 m/s squared‚ 4.32 m/s squared‚ and 5.11 m/s squared. It’s possible to use any two points to figure out and calculate acceleration due to gravity. Sir Isaac Newton

explained by Newton’s three laws of motion. They explain something different of the motion of an object‚ put together they explain everything. In order they are; Newton’s First Law: The law of inertia; Newton’s Second Law: The law with the concept of acceleration; Newton’s Third Law: The Law of Action & Reaction. Newton’s 1st law states that any object at rest will remain at rest or if its moving it will remain moving at a constant speed until force is has acted upon it or is exerted on it. For
