Question
I want to get a Newton's law sketches based on this scenario.
Also, if something got wrong, please correct them.
scenario
Net Force
Net Force Explanation
Newton's Law
Law Explanation
A book sitting on a table
0
Weight – Normal reaction
3rd law
Normal reaction is equal and opposite to weight of the book
A puck sliding across frictionless ice
0
It is sliding without any force
1st law
The puck will slide freely until disturbed
A child sitting on a merry-go- round turning at constant speed
Mv^2/r
Centrifugal force will push the child outward
1st law
Centrifugal force is caused by change in direction of motion.
A man leaning against a wall
0
Leaning force-normal reaction
3rd law
The force of the leaning man is balanced by the normal reaction given by the wall
A rock falling at constant terminal velocity
0
Constant velocity means no acceleration and hence no Force
2nd law
As F = 0; from F= ma, a =0
A car driving around a curve at a constant speed of 40 mph
Mv^2/r
Centrifugal force will push the car outward
1st law
Centrifugal force is caused by change in direction of motion.
A man pushing a box across a frictionless surface
F=push
The box will feel the force equal to that applied by the man and accelerate
2nd law
F = ma
A soccer ball placed on the grass
0
Weight – Normal reaction
3rd law
Normal reaction is equal and opposite to weight of the ball
Air inside and outside of an inflated balloon
0
The pressure of air inside is more. But elasticity of the balloon and outside pressure together balances it out
3rd law
The material of balloon gives tension required to hold the air as per 3rd law.
