science forces and motion

A vegetable vendor applies force to push the cart, a driver applies force either to stop the car or to change the speed or direction of motion and a football player kicks the ball to set it in motion..

A vegetable vendor applies force to push the cart, a driver applies force either to stop the car or to change the speed or direction of motion and a football player kicks the ball to set it in motion. In all the above examples, the force applied on ..

Force is the external agent that changes the state of rest or uniform motion of a body along a straight lin..

Introduction - We have learnt about the motion of objects based on the definition of displacement, velocity and acceleratio..

Kinematics deals with the study of motion without taking into account the cause of motion.Dynamics is concerned with the cause of motion, namely force..

Question 1 - Question: Define force. Answer: Force is an external agent or influence, which changes or tends to change the state of rest or state of uniform motion of a body in a straight lin..

According to Newton's first law of motion every body continues to be in its state of rest or uniform motion along a straight line unless an external force acts on it. This means that a ball moving on a horizontal surface should continue to move indefinitely as no ..

Force of Gravitation - Drop a stone from a height. What do you observe? The stone which was initially at rest starts moving towards the ground and attains a maximum speed just before it touches the ground. The stone is not moving with uniform speed. Its speed keeps changing at every insta..

Newton's second law of motion gives a quantitative definition of force. Impulse Mathematical representation of Newton's second law of motion is or When the time of application of force is short then Ft is defined as impulse. Impulse is a large force..
