Is rice or sand heavier?
Of course sand is lighter than rice.To answer your question,I went to my backyard to take sand and weigh it with rice.So rice is the answer. if you do not believe ,try it yourself. By :Jasmine Ng Jia Jia age:6
What is the relationship between mass and a object?
Assuming the only difference is mass and that two objects have the same shape and size, it will take longer for the heavier object to reach terminal velocity than the lighter object. The terminal velocity of the heavier object is greater than that of the lighter object. Since the two objects accelerate at nearly the same rate at slower velocities, the time to reach terminal velocity will increase as weight or mass of the object increases. However I would not expect the increase to be a linear proportion since the drag is proportional to the square of the velocity.
Does vacuum packing making things lighter?
No, because vacuums only take out the air. The clothes are still affected by gravity and have the same mass. Matter can neither be created nor destroyed. The only change is the density due to removed air which can make the items heavier per volume
Does the weight of the car affect the speed of the car?
Yes...a heavy car will accelerate slower, take longer to stop and ultimately have a lower top speed then if it were lighter. The first two are correct but the last is wrong. The simple fact that the car IS heavier means there will be more kinetic energy achieved over a longer time to very fast top speed usually occur in heavier equipped cars with the correct type of engine. The fastest cars (the speed record holders) start slowly but gain very fast speed weigh in and more than 15,000 lbs. That is 3 to 5 times heavier than the typical car.
Does a heavier object always have more inertia than a lighter object?
Inertia is "rotary momentum"; an object's ability to continue spinning when a decelerating force is applied.Just as a heavy object takes more effort to stop from the same speed as a light object, so does a heavy object take more effort to stop from turning at the same speed as a light object.So assuming they are turning at the same angular velocity, the heavier one has a larger inertia. Otherwise, remember that inertia is also proportional to angular velocity.
What happens when you take a rock from earth to the moon?
The earth becomes a litle lighter and the moon becomes a little heavier.
If you have ten barrels 9 filled with one oz balls and one with 2 oz balls With only one weighing how do you find the barrel with two oz balls?
->Take one ball from barrel one, two from barrel two, three from barrel three, etc. Weigh the balls. The number of ounces over 55 ounces will indicate which barrel has the heavier balls. If the weight is 60 ounces, barrel 5 has the heavier ones.
How do you replace a cigarette lighter in a 1993 ford escort?
Take the lighter out. Reach behind and disconnect the wiring and then unscrew the back of the lighter a thing called a barrel connector. It is a cylindrical lighter fastener on the back side which fastens the lighter assembly to the car. Turn it counter clockwise as looking at it from the rear.
How do you find the right pumpkin on great pumpkin poptropica?
Weigh 2 pumpkins, starting on the left. The lighter one will go up, the heavier will go down. Take the lighter one off and replace it with the third one, and after each successive weighing, keep the heavier one on the scale. You have to weigh all 7.
Why will go down the ramp faster a light object or a heavier one?
a lighter one because it doesn't take long for it to get going but, if you wanna know which one will go farther it would be the heavier one because it has more momentum.
Does vacuum makes things lighter?

What can gases do that solids cant?
They can take the shape of their container, and some are able to rise above air (some gases are lighter and some are heavier than room air.)
Why is a Boeing 747 always heavier at take-off than at landing?
The 747 is lighter on landing because of the fuel it burned off during flight. This is true for all planes.
Can you dive when taking morphine?
don't take morphine while diving because it causes problems to your lugs and makes your breathing heavier
What is different about a bird's bones?
the bones are hollow. makes the bird a lot lighter and thus generally suited to take flight!
How do you take the barrel off of a excel single barrel shotgun?
Take it to a gunsmith
Why Is it harder to stop a heavy football player rushing the ball than it is to stop a lighter one?
Because the heavier football player has a much higher momentum which is product of mass and velocity. To cancel the momentum of a heavier football player one must achieve the same momentum at impact. A lighter player can only do that by increasing his velocity.Momentum = mass x velocityIf a football player weighed 100 Kg and was traveling at 5 m/s (11 miles per hour). A 50 Kg person would have to impact the heavier football player at a speed of 10 m/s (22 miles per hour) to cancel the inertia of the heavier football player.As the heavier football player goes faster it becomes increasingly difficult to stop them. You can also take several lighter players by combining their mass to stop the forward momentum of the heavier football player.
