It takes less effort to throw a marble than a Basketball because a marble has less mass and inertia, making it easier to accelerate and release. The smaller size and weight of the marble mean that you need less force to get it moving compared to the larger and heavier basketball.
Because the Basketball weighs more than the marble ------------------------------------------------------------------------------------------ Most regular size, glass marbles weigh less about 0.16 ounces. A basketball weight about 22 ounces. When you throw something you have to accelerate its weight (mass) out of your hand, and a property of matter called "inertia" resists you. The size of the inertial resistance is directly dependent on the mass of the object, the bigger the inertia (mass) the bigger the resistance. Because of this it takes more effort (energy) to accelerate the heavier basketball compared to the lighter marble.
That depends how large the piece of marble is, and how fast each is moving. If you take a regulation basketball and a basketball made out of marble, and throw both of them with the same speed, the marble has more kinetic energy. But if your throw is any good, they both follow the same arc, and they both sink, for a total of 4 points.
No, an object with less volume takes up less space compared to an object with more volume. Volume refers to the amount of space an object occupies, so the less volume an object has, the less space it will take up.
A lever is a tool used to help you exert pressure on something, usually in order to move or lift it. Levers have three main parts: effort, which is the part that you focus your strength on; resistance, which is the something you are trying to move; and a fulcrum, which is the pivot point of the lever that allows it to focus your strength to accomplish the task. On a wheelbarrow the handlebars are the effort, the bucket where you put stuff is the resistance, and the wheel is the fulcrum. You use your strength to lift the handlebars, causing the wheelbarrow to pivot on the wheel to move the load within the bucket area. The end result is that you get to move whatever it is with less work than it would take if you were lifting and carrying the same items without the help of a lever.
To calculate the effort required, first determine the input force needed to lift the load by dividing the load (300N) by the mechanical advantage (velocity ratio of 5). So, 300N / 5 = 60N. Next, take into account the efficiency of 60%, so the effort required is 60N / 0.60 = 100N.

The gravity on the moon is much less than that of Earth. Thus, even a small step requires much less effort than on Earth. If astronauts were to take large steps, it would waste energy needlessly and probably take more effort.
Marble is a rock that can take a highly polished lustre - especially black or white veined marble.
mine is a 52in and it only took me less than a hour.

The sharper the edges, the easier is the cutting and piercing, and will take less effort. Blunt tools take more effort and are liable to slip, causing an accident.
Marble is relatively soft (calcite, the predominate mineral in marble is a 3 on the Mohs hardness scale) making it easy to work with, and the intertwined mineral crystalline structure from its recrystallization from limestone or dolomite also makes it less likely to fracture when struck with a tool. Marble will also take a polish, and has a translucency that gives it a pleasing appearance.

take a tunnel slide the marble in the toy box
It'd take much less time and effort if you just looked it up on Google, you know...
