Objective : a) To determine the relationship between velocity and time b) To determine the acceleration of the motion of the trolley c) To find the constant force exerted on the trolley

Introduction: Newton 's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased. Force is equal to mass times acceleration (for constant mass). So ,An object will accelerate in the direction of any net force applied to it.
The greater the force, the greater the acceleration. The greater the mass, the slower the acceleration. This means that the rate an object is slowing down or speeding up (acceleration) depends on how hard it is hit, pushed, or pulled (force) and the mass of the object. This means that the rate an object is slowing down or speeding up (acceleration) depends on how hard it is hit, pushed, or pulled (force) and the mass of the object. Let’s take a look at some examples to learn more about Newton’s Second Law. A truck hits a car; the car moves forward. The truck provides the force, the car is the mass, and the acceleration is how quickly the car (mass) moves forward. The larger and heavier the car

Experiment 1: Simple Harmonic Motion Dominic Stone Lab Partner: Andrew Lugliani January 9, 2012 Physics 132 Lab Section 13 Theory For this experiment we investigated and learned about simple harmonic motion. To do this we hung and measured different masses on a spring-mass system to calculate the force constant k. Simple harmonic motion is a special type of periodic motion. It is best described as an oscillation motion that causes an object to move back-and-forth in response to…

Interpretations: 1. The time required for the objects with different masses to fall equal distances was equal. 2. The average speed of the two different masses was quite similar, within one tenth of a second of each other. 3. Yes, because physics theory says that objects free falling, where the only force acting on them is gravity, accelerate at the same rate no matter what their mass is. 4. The change in spacing of the dots tells us that the speed of the object is increased as it falls…

The Relationship Involving Acceleration, Net Force, and Mass Giho Park Purpose The purpose of this lab investigation is to observe the relationship among the net force, mass, and acceleration of an object. Hypothesis/Prediction Part A If the net force increases with a constant mass, then the acceleration would increase, because the force would push the object to increase the velocity. Part B If the mass of the cart increases with a constant net force, then the acceleration would…
