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
