Through what three ways can we control the motion of our cars?
Seat belts protect you from the impact of a collision, not from speed or acceleration.
4m/s^2
Every action has an equal and opposite reaction.
It goes to the heart of Newtons laws: an object in motion will tend to stay in motion unless an outside force is applied. Force is just a measurement of how much an object 'wants' to stay in motion. The total energy (velocity and mass) of an object measures the resistance to change an object has. Given a perfect system two cars of the same mass moving at the same speed heading towards each other will collide and stop - they cancel each other out. Force is a way of saying what energy it will take to cancel the motion of an object out. You can use a slower, heavier object to counter the motion OR a faster, lighter object to cancel the motion. F=MV and not F=M+V is because the acceleration is to the whole object (applied all over) you can't add a scalar and a vector (mass is the scalar.) You can however multiply a vector by a scalar.
because newtonas lawis andobjectthat stays in motionwill like stay in motion thereforethe cars afterthey getgettherespeedwill probably keep going until the outer force( friction) acts to slow it down
olden day cars have no safety belts
There are "v" belts, "serpentine" belts and "timing" belts.
Yes, there are "v" belts, "serpentine" belts and "timing" belts.
the heavier one will go faster because of newtons first law of motion.
bumper cars, hockey puck, rocket launch, swimming, rowing in a boat. for example if you run into a wall and you use force on hitting it, the wall will use the same force to push you back, that why you bounce off the wall with the same force as you hit it.
Newton's laws of physics are three different physical laws. The one that is best demonstrated through the motion of bumper cars is the third law, as the two bumper cars would push together.
Newton's third law of motion states, "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body." An example of Newton's third law of motion is two cars in a head-on collision.
Usually three, but it really depends on the age, number of options, and manufacturer. However, all cars have a timing belt. All cars have an alternator/accessory belt. Some cars have balance shaft belts (ie Porsche 944), some cars have fan belts (older cars), some cars have power steering belts. It is usually pretty easy to tell by having a glance under the hood of the automobile.
