Does diameter affect velocity?

In the low-density/high-speed domain, drag is proportional to cross-sectional area, so doubling the diameter would quadruple the drag force. If you’re looking at just terminal velocity, that’s inversely proportional to the square root of the drag force, so it’s a linear inverse relationship with diameter.

Does the size of a ball affect the speed?

Our results show that the size of an object affects the perception of its speed. In particular, smaller objects appeared to move faster in translational motion.

Does velocity increase or decrease with diameter?

The mass flow rate will remain the same. For an incompressible fluid like water, that means the volumetric flow rate will stay the same. However, that means that the velocity of the flow changes. In your example, the velocity decreases when the diameter increases.

Why does the velocity of the ball change when hit?

As the ball falls it hits air particles which causes an upwards force in the opposite direction to its fall. The resolved force is still downwards so the ball still accelerates but at a slower rate.

How many times the velocity of the ball changes?

Answer: The velocity of football changes four times. First, when a football player kicks to another player, second when that player kicks the football to the goalkeeper.

What is the effect of changing the type mass of the ball on the speed of the ball?

If the same force is applied to two objects, the object with the smaller mass will change speeds more quickly. For example if a soccer ball and a bowling ball are thrown with the same force the soccer ball will speed up faster.

What affects the speed of a bowling ball rolling down lane?

A ball thrown down the lane will slow down over its course. The main cause of this is Friction. The magnitude of the friction between the bowling ball and bowling lane depends on what the surfaces are made of and the amount of oil on the lane, if there is any at all, and the mass of the ball.

What determines the final velocity of the ball in baseball?

The hitter has no control over the pitched ball speed, and while it may vary considerably from pitch to pitch we’ll assume that it is a constant. The only two remaining variables which determine the final velocity of the ball are the mass of the bat, m2 and the initial speed of the bat, v2b.

What is the before and after velocity of bat and ball?

After the collision (subscript “a”) both bat and ball have positive velocities. The before and after velocities and the masses of bat and ball may be related to each other through the physical relationship known as the conservation of linear momentum. Linear momentum is the product of the mass and velocity of an object, p = mv.

Why are the properties of a baseball ball treated as constants?

The properties of the ball may be treated as constants since they don’t change during a turn at bat. The hitter has no control over the pitched ball speed, and while it may vary considerably from pitch to pitch we’ll assume that it is a constant.

What is the change in kinetic energy during a baseball collision?

The change in kinetic energy includes information about the velocities of the ball and bat before and after the collision. During the collision the ball undergoes a significant amount of compression, and damping forces convert much of the ball’s initial kinetic energy into heat.
