Why is the middle seating most comfortable?

Why is the middle seating most comfortable?

The average position of the weight of the object is considered as the center of gravity. The position of center of gravity of the body affects the stability of that body. As the middle section of bus is very close to center of gravity of the bus in comparison to that at ends, so the middle seating is more comfortable.

Why is the center of mass of a baseball bat not at its midpoint?

The CG of a baseball bat is not at its midpoint because the bat’s weight distribution is not symmetrical. Since there is less weight at the handle end, the center of gravity of the bat is farther from the handle than the heavier end.

Why is it easier to balance a hammer by the handle?

Consider balancing a hammer upright on the tip of your finger. Easier on the right, because it has more rotational inertia (heavy part further away from your finger), so is more resistant to a rotational change.

Where do you expect the center of mass of a baseball bat to be?

Slowly pull the fingers together. When the fingers meet they will be underneath the center of mass of the bat. The center of mass is not halfway between the ends of the bat.

What happens to the center of gravity of a glass of water if you push a ping pong ball underneath the glass of water the CG _____?

What happens to the CG of a glass of water when a table tennis ball is poked beneath the surface? When you poke a table tennis ball into a glass of water, the CG of the system rises. This means that the gravitational potential energy of the system rises.

Why is it easier to balance a hammer upright handle on your fingertip and the head at the top?

Why is it hard to balance a ruler on your finger?

It is not possible to balance the ruler unless its centre of gravity is over your finger. You can find the centre of gravity of the ruler by sliding your fingers from the ends towards the middle. Friction makes sure that when your fingers meet they are both supporting the same amount of weight.

Where do you expect the center of mass of a baseball bat to be halfway between the ends of the bat nearer the lighter end or nearer the heavier end explain your answer *?

Would you expect the center of mass of a baseball bat to be located halfway between the ends of the bat, nearer the lighter end or nearer the heavier end? Since more of the mass of the bat is located near the heavier end of the bat, the center of mass of the bat will be located nearer the heavier end.

Where is the center of mass of a baseball?

The center of mass of a baseball is at the center. The center of gravity of a baseball is at the center. The center of mass and gravity for a baseball bat are closer to the bat head where there is more mass.

Why is it easier to hang by your arms than it is to do a handstand?

Why is it easier to hang by your arms below a supporting cable than to do handstands on a supporting floor? When you hang by your arms below a support, you are in stable equilibrium. Your CG is below your point of support. You don’t even think about “falling over” in this situation.

What is suggested by a star that wobbles?

The slightly off-center barycenter is what makes the star appear to wobble back and forth. Planets around other stars—called exoplanets—are very hard to see directly. They are hidden by the bright glare of the stars they orbit. Detecting a star’s wobble is one way to find out if there are planets orbiting it.

Why a hammer is perfectly balanced on tip of a finger?

Where is the least bumpy seat in a bus?

The very back seat is the worst. Whereas, on the London bus above, the middle front wheels are shifted rearwards. The best seat it the one directly behind the middle doors. The upper deck of double deckers, like this one, also tend to be less bumpy but more sway. So if you suffer from motion sickness, stay on the lower floor.

Which is the best seat on a bus?

The front wheels are very near the front, but the rear wheels are well forward from the rear of the bus. The mid point between the wheels is the best. That is the seat above the word “schools”, which in this bus happens to be the front seat on the right hand side.

Why is the back of a bus louder than the front?

The back wheels are usually several feet further from the back of the bus than the front wheels are from the front. So, when going over bumps or around corners, the rear of the bus swings through a greater arc. Therefore, any sudden movements (going over bumps etc.) are amplified for passengers sitting at the back of the bus.

Where is the best place to sit on a school bus?

You don’t want the centre of the bus, you want the centre of the wheels. For example, the school bus above doesn’t have the wheels positioned evenly. The front wheels are very near the front, but the rear wheels are well forward from the rear of the bus. The mid point between the wheels is the best.
