Does the mass of bodies depend on their velocity? Is the mass additive if\nseparate bodies are joined together to form a composite system? Is the mass of\nan isolated system conserved? Different teachers of physics and specialists\ngive different answers to these questions because there is no ...
What is Mass Weight and Average speed - Mass is the amount of inertia a body possesses. It is an intrinsic property of a body. It is constant all over the universe. It is measured in kg. Mathematically, $Mass = density times volume
Another way of describing a vector like it’s a scientific thing is this: A tuple that has scalars (numbers or values from a dataset). According toBritannica, examples of scalars include density, energy, volume, time, and mass. The thing to know about scalars is that they don’t possess...

Where m is the mass of the object, M mass of the earth, G is the gravitational constant, R is the radius of the earth, and v is the escape velocity. It simplifies to: v = sqrt(2GM/R) or v = sqrt(2gR) Where g is acceleration of gravity on the earth's surface. ...
It is also defined as the velocity of zero time intervals. The initial velocity can be calculated using any equation of motion. Answer and Explanation: We are given the following data: The velocity of the vehicle is u=85m/s. The acceleration is {eq}a = -......

Determining the terminal velocity for an object dropped from a given height can be complicated. Some of the factors, such as mass and acceleration due to gravity, are straightforward, but it is also necessary to know the drag coefficient, a value that depends crucially on the shape of the ob...
