![]() When the object hits the ground, the impact force comes into action. ![]() According to Newton’s second law of motion, the acceleration developed by a body is directly proportional to the force. The acceleration increases as the object advanced towards the earth. ![]() When an object is thrown from a certain height, the gravitational pull of the earth helps it to develop acceleration. Similarly, the more be the acceleration with which the car moves, the greater will be the magnitude of the impact force. This means that the greater be the mass of the objects involved in the collision, the more will be the intensity of the impact force. The magnitude of the impact force depends on the mass of the objects involved in the collision and the speed with which the objects move. The speed achieved by the rocket finally helps it to escape the earth’s gravitational field and enter space.ĭuring a car crash, there exists a force between the obstacle and the car, which is known as the impact force. As per the second law of motion given by Sir Issac Newton, the force is proportional to the acceleration therefore, to launch a rocket, the magnitude of thrust is increased, which in turn increases the acceleration. This means that the harder you hit the ball, the faster it will move, thereby demonstrating Newton’s second law of motion in daily life.įor a rocket to leave the earth’s orbit and enter outer space, a force called thrust is required. The acceleration with which the ball moves is directly proportional to the force applied to it. This scenario justifies Newton’s second law of motion in real life by establishing a relationship between mass, acceleration, and force.Ī ball develops a certain amount of acceleration after being hit. Due to the inverse relationship between mass and acceleration, the person having more mass tends to move slower, and the person having less mass tends to move faster. Since mass has an inverse relationship with acceleration, the loaded cart tends to move at a slower pace than the empty cart.Ĭonsider two people, having different masses, walking together. This is because of the relation between the mass of the object, the force applied to it, and the acceleration produced. Pushing an empty shopping cart is easier than pushing a loaded shopping cart. This is because the mass of the car is less than the mass of the truck. It is easy to notice that after pushing a car and a truck with the same intensity, the car accelerates more than the truck. Newton’s second law of motion can be observed by comparing the acceleration produced in a car and a truck after applying an equal magnitude of force to both.
