Two cars having different weights are traveling on a level surface at different constant velocities. Within the same time interval, greater force will always be required to stop the car that has greater

The answer to the question is

Momentum

Explanation:

Momentum in physics refer to the attribute that a body has by virtue of its mass and velocity. It is found by multiplying the mass of the moving object and the velocity, hence

Momentum = Mass × Velocity = m·v

Newton first law of motion states that the force acting on an object is proportional to the rate of change of momentum produced

Therefore when we find the momentum of the two cars, the one that has the greater momentum will require the most force to stop it.

Momentum is a physics term; it refers to the quantity of motion that an object has. A sports team that is on the move has the momentum. If an object is in motion (on the move) then it has momentum
