### What is the differnce between mass and weight?

Weight requires the effects of gravity. An object's weight will change when the effects of gravity change (i.e., distance from the earth, immersing it in water, putting it in outer space). An object's "mass" a fundamental measure of the amount of matter in the object. It is generally thought to remain unchanging; however, approaching the speed of light, the relativistic mass of an object would change.

### How does mass affect speed?

== F=m*a Force = mass * speed a = F/m For the same Force F the speed is big for small mass the speed is small for big mass == The more mass something has, the more force is required to accelerate it to a given speed. The less mass something has, the less the force required to accelerate it to a given speed. Simple and easy. For a given amount of force, the less…

### Does gravitational potential energy depend on mass and speed?

On mass yes, on speed no. The formula for gravitational P.E. is: PE = mgh, that is, mass x gravity x height. On mass yes, on speed no. The formula for gravitational P.E. is: PE = mgh, that is, mass x gravity x height. On mass yes, on speed no. The formula for gravitational P.E. is: PE = mgh, that is, mass x gravity x height. On mass yes, on speed no. The formula for…

### If a solid mass travels at the speed of light and it passes through the suns ray to earth would it be seen?

A solid mass won't travel at the speed of light. A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun. A solid mass won't travel at the speed of light. A solid mass of any speed can block rays of light from the Sun, if it happens to pass in front of the Sun. A solid mass won't travel at the…

### Electrons move near the speed of light?

With very, very, very high energy, you can get electrons near the speed of light. But they will never reach the speed of light - this is due to them having mass. This is the type of work being done at Accelerator centers like in America (FERMI LAB) and in Europe (CERN). They speed the electrons up to near the speed of light then collide them into each other to learn about these effects of…

### Can any cards in yu-gi-oh be chained to any other card as long as it has the same or higher spell speed?

Mostly. Spell Speed 1 effects can't normally be chained to each other. You can get situations where two Triggered effects activate simultaneously, meaning you have a Spell Speed 1 effect at chain link 1 and 2. But ignoring Triggers, a player can't chain a Spell Speed 1 effect to another Spell Speed 1 effect, these can only start chains, not add to them. Spell Speed 2 effects can be chained to Spell Speed 1 or…

### How does mass affect velocity on cars?

The larger the mass a car effects the velocity in that you require a stronger engine to make it accelerate at the same speed of a lighter car. Having a higher mass, it will take longer for it accelerate as well as for it to decelerate. Two cars that collide that have the same velocity and masses will stop, while if ones mass his higher it will cause greater damage to the smaller one.

### What was the kinetic energy of each car before braking?

More information is needed. Once you have both the mass and the speed, you can calculate kinetic energy as (1/2)mv2 (1/2 times mass times speed squared). More information is needed. Once you have both the mass and the speed, you can calculate kinetic energy as (1/2)mv2 (1/2 times mass times speed squared). More information is needed. Once you have both the mass and the speed, you can calculate kinetic energy as (1/2)mv2 (1/2 times mass…

### How does mass and velocity increase or decrease kinetic energy?

Kinetic energy of a mass is directly proportional to two variables: its mass and speed. Many mistake kinetic energy as being proportional to mass and velocity; it is, in fact, mass and speed. (With all technicalities aside, the speed is the factor that matters in computing kinetic energy of an object or a mass). Kinetic Energy = 0.5mv2 (m = mass and v = speed of the mass) Therefore, if the speed of the object…

### What effects the distance a car takes to stop?

The speed; the quality of the braking system; the mass of the car; the time it takes the driver to notice a danger. The speed is especially important; other things being equal, braking distance is proportional to the square of the distance. That means that at twice the speed, the car will move 4 times as far while it brakes.
