is there a reason that if you throw a bal up in the air in a car, the ball doesn't hit the back window?

Question

i just want to know why if the car is moving why the ball doesn't move with it

Answer 1

It's called inertia - An object in motion stays in motion ( unless interupted by an outside force)

Answer 2

The ball is moving at the same velocity of the car and has kinetic energy equal to 1/2mVxV (one half its mass times its velocity squared). If you have two objects (balls) and toss them both up, one inside and the other outside the car, the ball outside the car will plow through the air and air resistance will dissapate its energy slowing it down. The ball inside the car is moving with the same velocity as the air inside the car and there is no air resistance to slow it down. If you toss the ball in the air while slamming on the brakes, the ball will move ahead and hit the stopped windshield.

Answer 3

without extra records, the in straightforward words excellent answer would favor to be: E. each and every of the Above If the forces appearing upon the ball contain atmospheric friction, then 'A'. If the vehicle is vacationing opposite, then 'B'. If through "open" you advise that in straightforward words the doorways and abode windows are unobstructed, then 'C', because the ball thrown instantly up would strike the roof of the vehicle and rebound at an perspective of competition equivalent to the perspective of occurrence, which may be without delay in his hand if the vehicle replaced into on a aspect floor and the roof replaced into also completely aspect. If through "open" you advise that in straightforward words the doorways and abode windows are unobstructed and the vehicle had 2 flat tires on one section or the different, then 'D'.

Answer 4

Same reason why when you throw the ball up in the air in the street, it doesn't go flying through your neighbor's house.

The ball is already at rest to the frame of reference of the car, just as the ball in the street is already at rest with the street that is circling the earth at 1,000 mph.

Try throwing the ball up in the air, and just as it leaves your hand, slam on the brakes. Wait, on the other hand, don't try this. =)

Answer 5

the basic idea is, the momentum of a body remains same(and this is the law of inertia). momentum is velocity*mass of the body..
so at the time of throwing the ball up, the ball will keep going at the speed at which it was travelling earlier.. but iif u decelerate, or accelerate the car, the ball will hit the front/back window..
but this is possible only if wind drag is zero.. ideal conditions.

Answer 6

Because the ball has inertia moving forward from being in the moving car.

Answer 7

Because everything inside the car, the ball, you, your CDs, your drink is moving at the same speed the car is.

Answer 8

b/c the car and the ball are moveing at the same speed.
if you were to throw the ball high enough it would eventually move back behind the car if the car was still moveing.

Answer 9

ok, say u r going 55mph everything in the car is going that fast including the air in the car, unless there is a force pushing the ball back it wont matter how fast you go.

Answer 10

The windshield blocks the force of pressure and friction horizontially inside of the car
