If you are in a moving car and if you throw a ball vertically up why does the ball fall in your hand?

Because both You and the ball (and everything else in the cabin for that sake) are moving with the same speed as the car :)

Why does a ball fall to Earth when you throw it up in the air?
gravity
A person jumping off a moving bus tends to fall forward?
yes they do. this is due to momentum. same way as when you throw a ball. it hits the ground and keeps rolling forward.
What explains why the cart always catches the ball and the ball doesn't fall behind the moving cart?
Because the ball and the cart are moving at the same forward speed.
What is an example free fall?
A rock that is dropped, and a apple falling from a tree.Hold a ball in your hand, stretch out your arm, and drop the ball. As it is moving towards the ground, it is in free fall.

What are some tips for pitchers on keeping the ball low in the strike zone?
It may sound stupid, but throw less heat. If you throw softer, the ball has more time to fall before it reaches the plate.
If a ball is thrown vertically upwards and the acceleration on it is neg 9.8 due to gravity will the sign change when the ball changes direction to fall back down thus giving an acceleration of 9.8?
Yes. On the way up, negative acceleration is taking place because the ball is moving up and gravity is acting in the opposite direction. On the way back down, acceleration is positive, and the object starts at rest.
How do gravity and friction work together to cause a ball moving throgh the air to fall toward earth?
Gravity is the only thing that makes the ball fall toward Earth. All friction does is slow the rate of the fall slightly, and make it take longer.
How will the path of the ball appear to you if you accidentally drop a ball while inside a moving bus?
If the bus is moving at a constant horizontal velocity relative to you and the ball, there is no horizontal acceleration and therefore no horizontal force. The only force acting on the ball is gravity, which is vertical, so the ball will just fall straight down next to you.
How does a roulette ball stop?
The roulette ball stays in motion due to centrefugal force. Since the ball is moving fast it "wants" to just go straight (Newton's 1st law) but the contact force of the metal track exerts an inward force that keeps it moving in a circle. Eventually, as the ball loses momentum, the force of gravity will be greater and the ball will then fall into a pocket.

What happens to a falling objects acceleration?
The gravitational pull of earth makes it so that a falling object will fall at 9.81meters/second, and accelerate at that speed. So if an object falls for 2 seconds, its going 19.62m/s. Also, if you throw a ball straight up into the air from ground level (we are currently ignoring air and wind resistance) Then when it gets to the peak of the arch, it will be moving at 0m/s vertically. This means that when the ball gets back to the exact elevation that you threw it from, gravity will have sped it back up to the EXACT same speed that it had when you released from your hand, only now its going the other way.
