Which accident will cause more damage to the green car? In both collisions the green car is traveling at 50 mph
In the first collision the green car hits another car (head on) also going 50 mph
In the second collision the green car going 50 mph hits a brick wall.
Which collision do you think will cause MORE damage to the GREEN car. Explain your thinking

answer; equivalent to a one(1) horsepower motor;

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
