Yes, the extra weight of the couch will give it a greater maximum velocity, as well as rate of acceleration, on and off-piste.
Longer and wider skis means a greater area of contact with the snow, causing greater acceleration: Provided the skis are reasonably waxed/ prepared. If the ski bases are dried out, they may actually slow you down, since a dry ski base will have a braking, friction effect.
No lighter things do not fall faster than heavier things. In a vacuum they will fall at the same speed. Normally the heavier thing will fall down faster because of its weight. Sometimes the lighter thing falls faster depending on the air resistance.
It depends on the lorry, if it's heavier or carrying heavier things then it will have to travel slower. If it's lighter or carrying lighter things then it can travel faster.
Yes, because the Friesian is lighter and the Clydesdale is heavier.
No, lighter gases effuse faster than heavier gases. This is because the rate of effusion is inversely proportional to the square root of the molar mass of the gas. Lighter gases have lower molar masses, which results in faster effusion speeds.
The lighter strings vibrate much faster than the heavier ones when the bow is drawn across them. This faster or higher frequency of vibration emits the higher pitched sound.
Heavier stars will usually burn faster than lighter stars.
The lighter the dragster is for its horsepower, the faster it will go. This is why the front frames and tires are so relatively flimsy.
Assuming the parachutes are the same size, then yes.
In most cases, heavier things do not necessarily go faster than lighter things. The speed at which an object moves is typically determined by factors such as the force applied to it, the surface it is moving on, and air resistance. In some cases, heavier objects may have more momentum and be more difficult to stop once in motion, which can give the impression that they are moving faster.
because the heavier person has more initeria and therefore the forces that would slow the slider down i.e friction, wind resistance, whatever, have less effect on a heavier person that a lighter person
Heavier particles will settle to the bottom first due to gravity pulling them down faster than lighter particles. This process is known as sedimentation and is commonly used in industries such as wastewater treatment to separate solid particles from liquid.
Well, if in a gas you have a mixture of heavier and lighter particles (atoms or molecules, really), the lighter particles will tend to move faster than the heavier particles. The general tendency is for any such particle to have the same energy (mainly kinetic energy). Similarly, in a liquid solution, lighter particles will tend to move faster.
