Question

illustrate one example for each of the tree laws of motion. ​

Answer 1

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. 3rd law = for every action (force) there is an equal and opposite reaction (force). eg - a swimmer pushes water backwards (action) . the water pushes him forward (reaction)

Answer 2

Example of 1st law of motion:
When we are travelling in a bus, our body is also travelling with the velocity equal to that of the bus. If the bus stops suddenly our body tends to continue in the same state of motion due to inertia and we tend to fall forward.


Example of 2nd law of motion:
When a glass vessel falls from a height on a hard floor, it comes to rest instantaneously (i.e., in a very short time) so the floor exerts a large force on the vessel and it breaks. If it falls on a carpet (or sand), the time duration in which the vessel comes to rest, increases and so the carpet (or sand) exerts a less force on the vessel and it does not break.


Example of 3rd law of motion:
When a fish swims in water, the fish pushes the water back and the water pushes the fish with equal force but in opposite direction. The force applied by the water makes the fish to move forward.
