ANSWER: I'm assuming by "mousetrap" car, you mean small car. Probably pretty obvious at that point that your car would have a.....small mass.
Mass
Usually small metals (e.g magnesium etc) have small capacit but large mass Hope it helps :)
Note: Kilogram is a unit of mass, not of weight.A small bag of sugar, salt, or flour might have a mass of 1-2 kilogram; a small jar of water will also have a mass of about 1 kilogram.Note: Kilogram is a unit of mass, not of weight.A small bag of sugar, salt, or flour might have a mass of 1-2 kilogram; a small jar of water will also have a mass of about 1 kilogram.Note: Kilogram is a unit of mass, not of weight.A small bag of sugar, salt, or flour might have a mass of 1-2 kilogram; a small jar of water will also have a mass of about 1 kilogram.Note: Kilogram is a unit of mass, not of weight.A small bag of sugar, salt, or flour might have a mass of 1-2 kilogram; a small jar of water will also have a mass of about 1 kilogram.
small
The same force applied to a small mass will cause a larger acceleration compared to a large mass since acceleration is inversely proportional to mass (F=ma). This means the small mass will experience a greater change in velocity in response to the force compared to the large mass.
An electron has a very small mass compared to larger particles like protons and neutrons. Its mass is approximately 1/1836 times the mass of a proton.
stars that are dim probably have both a small mass and a larger radius.
An object with a high density, such as a lead ball, can have a small capacity (volume) but a large mass. This is because density is the ratio of an object's mass to its volume, so objects with high density have a lot of mass packed into a small space.
a milligram is the mass a very small insect, the mass of a toothpick, or the mass of a string
Mass A rather small mass, such as a dose of medicine or the mass of the air in a jar.
Small force on small mass :When we exhale the air the force of exhaled air is less. Tiny particles of less masses are present in the nearer air and they start moving with large velocity. On Large mass : it's well explained in pascal's law. From that we can apply small force on larger mass .
