Answer 1

${ \huge{ \bf{ \underline{ \red{Answer}}}}}$

Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.

• Newton 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. This is normally taken as the definition of inertia.If an external force is applied, the velocity will change because of the force.

Examples:-

1. An astronaut who has their screwdriver knocked into space will see the screwdriver continue on at the same speed and direction forever.
2. With no outside forces, a moving object will not stop

• Newton Second Law:-

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.

Examples:-

1. When a force is applied to a car, the change in motion is proportional to the force divided by the mass of the car.
2. If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass.

• Newton Third law:-

Third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A.

Examples:-

1. When you jump off a small rowing boat into water, you will push yourself forward towards the water.
2. When air rushes out of a balloon, the opposite reaction is that the balloon flies up.

Answer 2

The laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object's mass. (3) For every action, there is an equal and opposite reaction.
