Short explanation :

1)Newton's First Law, also known as the Law of Inertia, states that an object will remain at rest or in uniform motion unless acted upon by an external force. When applied to a car climbing a steep hill, this means that the car will not start moving uphill on its own. The engine provides the external force necessary to overcome inertia and the gravitational pull that resists the motion.

As the car climbs, the engine must exert enough force to counter both gravity and friction. If the force from the engine is greater than the opposing forces, the car will accelerate uphill. If not, the car may slow down or stop.


2) Newton's Second Law of Motion states that the acceleration of an object depends on the net force applied to it and the object's mass, expressed by the formula F = ma (Force equals mass times acceleration).

When pushing a car from the front:

The amount of force you apply determines how much the car will accelerate.
A larger car (with more mass) requires more force to achieve the same acceleration as a smaller car.
If you push harder, the car will accelerate faster, provided friction and other opposing forces remain constant.

3)Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction.

When two cars collide head-on from opposite directions:

The force that car A exerts on car B is equal in magnitude but opposite in direction to the force that car B exerts on car A.
Both cars experience the impact force, but in opposite directions.
The reaction forces occur simultaneously, causing damage or deformation to both cars, depending on their speeds and masses.
