Tell minimum 10 applicatins in our daily life where the three laws of motion by Newton are applied.
Dear Student
Following are few application, you can add more by studying these consequences of each law:
Consequences of Newton's Ist law of motion :
1. If no force acts on a body, then the velocity of the body cannot change , i.e., the body can not accelerate.
2. Acc. to this law, a body continues to be in its state of rest or of uniform motion, along a straight line unless it is acted upon by some external force to change the state.
Application of Newton's Ist law of motion :
1. Without the application of an external force, a body cannot change its direction of motion, i.e., it continues to move along the same straight. For example , to turn a car moving over a straight road, we have to apply the force on the steering wheel of the car.
2. Without the application of an external force, a body at rest continues to be at rest. This part is self evident. For example, we find in day to day life that every object continues to lie where it is , unless we move it.
Consequences of Newton's IInd law of motion :
1. No force is required to move a body uniformly along a straight line.
According to newton's second law of motion
F = ma
when body is moving uniformly along a straight line, and there is no force of friction, acceleration/ retardation of the body, a = 0.
Therefore , F = ma = 0
i.e., no external force is required.
The second law is obviously consistent with the first law.
2. Accelerated motion is always due to an external force.
Application of Newton's IInd law of motion :
1. The motion of a body may be accelerated under the following three conditions :
(a) Speed of a body may change. For this , force has to be applied in the direction of motion or in a direction opposite to that of motion.
(b) Direction of motion of a body may change . For this, force has to be applied in a direction perpendicular to the direction of motion of the body.
Consequences of Newton's IIIrd law of motion :
1. Forces always occur in pair as a result of mutual interaction between two bodies.
2. To every action, there is always an equal and opposite reaction.
Applications of Newton's IIIrd law of motion :
1. Walking : While walking , a person presses the ground in the backward direction (action) by his feet. The ground pushes the person in forward direction with an equal force (reaction). The component of reaction in the horizontal direction makes the person move forward.
2. Firing from a gun : When a gun is fired, the bullet moves forward (action). The gun recoils backwards (reaction).
