Why does it take less effort to throw a marble than a 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.
Is there anything smaller than a neutrino?
Depends what you mean by "smaller." The mass of a photon is smaller than even that of a neutrino. At a sub-atomic level, concepts like "volume" or "size" become almost meaningless, so it is difficult to say whether the "size" of a neutrino is greater or less than that of, say, an electron.
Suppose two blocks of identical shape and size were placed in water Block A is made of wood and block B is made of iron How would the buoyant force on these two objects compare?
Mass is the measure of inertia .sliding friction depend on mass. so their ratio of mass will be 1:5
The more of this an object has the greater the objects inertia?
Simple Answer:Mass and inertia are essentially the same thing.Better Answer:Inertia is a characteristic of any physical object and mass is the quantitative measure of the characteristic.This is embodied in Newton's first law of motion. We can say this as follows.An object in motion will resist a change in motion and a body at rest will remain at rest unless acted on by some external influence. This property of maitaining a state of motion is called inertia in physics. The external influence that can change a state of motion is a force. To say that some objects resist a change of motion more than others is to say that some objects have more inertia than others.Fortunately, this characterization of inertia is more than qualitative. There is a precise physical measure of inertia and it is called mass.This is contained in Newton's second law of motion. We quantify the concept of motion by defining velocity. We quantify change in motion as acceleration. We quantify mass as the ratio of the acceleration to force.F=ma.m=F/a.The dramatic characteristic of the relationship is that if you quantify the mass of an object by applying twice the force, you get twice the acceleration and hence the same mass.To be slightly more specific we must also note that force and acceleration are both vector quantities and the above relationships are valid for both magnitude and direction of force and velocity.Note: Two comments are appropriate to be very technical. First, this explanation ignores the possible distinction between mechanical mass and gravitational mass. Secondly, the theory of relative has an equally significant understanding of mass that is not discussed here. These technical points do not invalidate the description above and may be ignored unless engaged in the most sophisticated and expert levels of discussion.
How are the size and mass of the moon different from that of Earth?
The moon is smaller than the Earth so that would mean the size is smaller and the mass is also smaller because the mass depends on the size of the object so the moon would have less mass than Earth.
Why does a star's gravity increase when it gets smaller?
no a stars gravity decreases as its size gets Smaller.
Meaning of definition of volume and mass?
Volume is the size of a solid and mass is the quantitative measure of inertia, or the resistance of a body to a change in motion.
Why the smaller the sugar size the faster the sugar dissolves in water?
almost in every reaction as the surface AREA gets smaller the reaction becomes faster.as the same time dissolution gets faster when the size of the sugar crystals gets smaller in water.
How big do comfort retrievers grow?
There are 2 basic size classes. The larger size gets to be about 45 lbs. The smaller size gets to be about 20 lbs.
Why cricket ball has more inertia than rubber ball?
because cricket ball has greater mass
Can inertia be measured in terms of numbers?
Inertia is a property of mass, and since mass can be measured (normally by kilograms) then inertia can also be measured. All scientific measurements are done with numbers, that is what we mean when we say that we measure something. If you are going to estimate a size without using numbers (as in, that's a really big apple) that is not a measurement.
What happens to the size of the thoracic cavity when the diaphragm contracts?
it gets smaller in size forcing the air out of the lungs
How does surface to volume ratio to the size of a cell?
As the cell gets bigger, the surface to volume ratio gets smaller.
how does surface to volume relate to the size of a cell?
As the cell gets bigger, the surface to volume ratio gets smaller.
