What would happen if more air is added to a ball?

As no energy is added to the ball, the ball bounces back with less kinetic energy and cannot reach quite the same height. A well-inflated ball bounces better because it has more air inside. This allows it to push back faster, reducing the contact time and contact area in a collision and thus reducing the heat produced.

When a ball is thrown straight up the acceleration at the highest point is?

An object is thrown upward with a speed of 14m/s on the surface of planet X where the acceleration due to gravity is 3.5m/s2. What is the speed of the object after 8.0s? Human reaction time is usually greater than 0.10s.

What happens to the ball when you throw up?

When throwing the ball up, you accelerate it and therefore you transfer kinetic energy to the ball, not giving it force. The only force acting on it is the gravitational force, pulling it downwards (which is why it slows down and stops momentarily at the apex, before coming back down).

When we throw a ball in the air it falls back why?

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 increases gas pressure?

An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure.

What happens to the pressure of a gas inside a container if the amount of the gas decreases?

Volume. Pressure is also affected by the volume of the container. If the volume of a container is decreased, the gas molecules have less space in which to move around. As a result, they will strike the walls of the container more often, and the pressure increases.

When a ball is thrown straight up and it is at its highest point what is true about its position?

When a ball is thrown vertically upward, the acceleration due to gravity always acts downward to the ball. When the ball is moving up the acceleration due to gravity will decrease the velocity of the ball and finally, the velocity will become zero at the maximum height.
