What is the relationship between weight and mass?
Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on that object. People often use the words “mass” and “weight” interchangeably because gravity is pretty much constant on Earth, so there isn’t a difference between their values.
What is the difference between the mass and the weight?
In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the force exerted on an object by gravity.
Why do things with lower density rise?
The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
Why does a ball moving upward slow down and falls back?
As you throw the ball up into the air, its direction is up, but the speed decreases due to the pull of gravity. The ball slows down, and at the very top of its flight, its velocity at that instant is zero.
What is the relationship between density volume and mass?
An object’s density is the ratio of mass to volume of an object. The mass is how much it resists acceleration when a force is applied to it and generally means how much of an object or substance there is. Volume describes how much space an object takes up.
Does heating increase mass?
Does adding heat energy increase an objects mass? Yes, it increases the average kinetic energy of the molecules in the center of momentum frame, which means the object’s mass increases.
Do heavier or lighter objects reach terminal velocity faster?
heavy objects will have a higher terminal velocity than light objects. It takes a larger air resistance force to equal the weight of a heavier object. A larger air resistance force requires more speed.) Therefore, heavy objects will fall faster in air than light objects.
How will an objects size and mass affect its terminal velocity?
An object with a large projected area relative to its mass, such as a parachute, has a lower terminal velocity than one with a small projected area relative to its mass, such as a dart. In general, for the same shape and material, the terminal velocity of an object increases with size.
Which object will hit the ground first?
Heaver objects fall faster. If you drop a heavy and light object together, the heavy one will get to the ground first.
