What is the difference between mass and momentum?

Answer 1

Mass is a fundamental measure of inertia; it measures the resistance of the body to changes in its motion. Thus, inertia is resistance to motion changes. Whereas, momentum is mass in motion, and, is defined as the mass times the velocity. Examples. A girl (or a Baseball) has a certain mass and, therefore, inertia. She can directly feel her body's inertia as the resistance she encounters when she changes her body's momentum, such as when she: * comes to a skater's stop, digging her blades into the ice, and feeling the ice pushing against her feet and legs, as she slows. * stopped at the bottom, laboriously starts her bicycle up a steep hill. * catches a fast baseball, stinging her hands, as the ball's momentum decreases abruptly to zero.

Answer 2

inertia is measured in energy 1/2 mv2

momentum is measured in Kilogram metres per second Kgm/s mv

momentum can be thought of as the first derivative of kinetic energy dependent on velocity.

Answer 3

Inertia is an object's unwillingness to change its trajectory, due to the object's momentum. Consider a car going 60 miles or kilometers per hour, straight down open road. All of a sudden the driver needs to make a sudden and sharp left turn.

What must the driver do to make this sudden turn? Why?

Answer 4

Momentum is the product of mass times velocity, p=massxv.
