Newton's Laws: Forces and Motion A force is a push or a pull. A force is a vector : it has a magnitude and a direction. Forces add like vectors, not like scalars. Example: Two forces, labeled F 1 and F 2, are both acting on the same object. The forces have the same magnitude F F F 12 oand are 90 apart in direction: F F F F F

given Vaisheshika Sutra in 600 BCE which describes the relation between force and motion. We first discuss the Newton‟s three laws of motion. First law Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.

motion. The First Law says that objects at rest and objects in motion will remain at rest or in motion, unless they are acted upon by an “unbalanced force.” The Second Law says that when a force acts on a mass, acceleration is produced. The greater an object’s mass is, the more force is needed to accelerate it.

SYSTEMS OF PARTICLES AND ROTATIONAL MOTION 107. The physical quantities, moment of a force and angular momentum, have an important relation between them. It is the rotational analogue of the relation between force and linear momentum. For deriving the relation in the context of a single particle, we differentiate.

the applied force may change both the direction of motion of the body and how fast it is moving. Newton defined the force acting on an object as proportional to the acceleration of the object. An impressed force is an action exerted upon a body, in order to change . its state, either of rest, or of uniform motion in a right line. 2

Forces and motion are one of the most important things in our lives, forces and motion make things move and stay still. Motion is just movement needing a force to act upon it. Pushing and pulling are examples of forces that can sped things up or slow things down. There are two types of forces, at a distance force and contact forces.

Multiple forces on an object add up to produce a net force. An object with a zero net force on it is either at rest or moving with constant speed. Inertia is a property of all objects with mass and represents the resistance of the object to change its motion. An object with a non-zero net force will change its motion.

motion will remain in motion (won’t experience a change in speed or direction) unless an external force pushes or pulls it. After Galileo came Isaac Newton, who also explored ideas about force and motion and, in the process, figured out some incredible things about our universe! In 1686, he introduced three laws of motion in one
