What happens if you throw a ball in a train?
When a person throws a ball up in a moving vehicle, say, a train, the ball does come straight back to thrower as though the train were at rest. So if the train moves with a constant velocity, the ball will exactly return to the thrower.
When a ball is thrown vertically upwards by a person in a moving train it comes back to his hand Why?
The reason is that at the moment the ball was thrown, the ball was in motion along with the person and the train, due to the inertia of motion. So during the time ball remains in air, both the person and the ball move ahead by the same distance. This makes the ball to come back to his hand on its return.
What happens when a ball is thrown up?
Once the body is thrown upwards, it goes up until the velocity of the ball turns out to be zero and the force exerted on it becomes zero. After that, the ball touches the ground with acceleration due to gravity and zero velocity. The acceleration that acts on the body is because of the gravitational force.
Where is a throw-in taken from?
The throw-in is taken from the point where the ball crossed the touch-line, either on the ground or in the air, though typically a referee will tolerate small discrepancies between the position where the ball crossed the touch-line and the position of the throw-in.
Where do throw ins take place on the field?
A throw-in in soccer occurs when the whole ball passes over the touchline on the side of the soccer field.
When we throw a ball in the air it falls back?
This is because the force of earth’s gravitational field is always directed downwards (towards the center of the earth. When the ball is thrown up, it is going against the earth’s gravitational field and so, the earth’s gravitational force pulls it back down, accelerating it downwards.
What happens when a ball is thrown in the air?
When you throw a ball up in the air, its direction/velocity on the way up, although it rises up into the air, is actually downward. On its way up, its speed decreases, until it momentarily stops at the very top of the ball s motion. Its acceleration is -9.8 m/s^2 at the very top.
