Question

Take 5 examples from your surroundings and give explanation based on Newtons laws of motion.

Answer 1

• If we try to push an empty cart and a cart full of bricks, it would be easier to push an empty cart than the cart full of bricks. This happens because the inertia of the cart full of bricks is more than the empty cart and by Newton's first law of motion we know that more the inertia, more force is required to change the state of rest of a body.
• If we push a bicycle and a car with the same force, the bicycle will have greater acceleration than the car because the bicycle has less mass compared to the car.
• When we place a book on table, the book does not fall. This is because the same amount of force is applied by the table on the book as is applied by the book on the table.
• Our walking is an example of Newton's third law of motion. When we walk we push the ground in backward direction with some force. The ground in reaction pushes us forward with the same force.
• When we shake a tree, the leaves of the tree fall to the ground. This is because the leaves were in the inertia of rest before shaking of tree. So when the tree was shook, they fall down to attain their inertia of rest again.
