No, the force of impact is not directly proportional to the speed of the car. In a collision, the force of impact is determined by the change in momentum, which is a combination of speed and mass. Doubling the speed does not necessarily mean quadrupling the force of impact.
True, the force of impact in a collision increases significantly with speed. This is because kinetic energy, which relates to an object's speed, increases with the square of the speed. So, tripling the speed of a car would result in nine times the force of impact in a collision.
Yes, the force of impact is proportional to the square of the velocity, so at 60 mph, the force of impact is roughly four times greater than at 30 mph. This is due to the increased kinetic energy at higher speeds.
Torque is the combination of perpendicular distance and weight; it is not a true force
When an object is moving in a straight line at constant speed, the forward force (such as thrust or propulsion) is equal to the backward force (such as friction or air resistance) acting on the object. This equilibrium of forces allows the object to maintain a constant speed without accelerating or decelerating.

Regarding Newton's first law the law of inerita, it is true to say that it describes the motion when a net force is zero:d -ajizzle my nizzle.
Probably not. The bulk of the labour force were peasants conscripted when the Nile was in flood and no work possible in the fields.
The opposite force to friction is momentum. Because friction stops an object from moving or slows an object down, momentum keeps it at speed.
Yes, it is true.
