What is the momentum p if the mass m is doubled?
Vzp
1) р
2) 2p
3) 4p

Correct 2) 2p

Explanation:

Momentum

Momentum is a measurement of mass in motion or how much mass is in how much motion. The symbol for momentum is p and is defined as:

p = m . v

Where m is the mass of the object and v is the speed. Note this is the scalar version of the formula because both p and v are vectors.

Suppose the mass of the object is doubled to 2m, then the new momentum is:

p' = (2m) . v = 2 m . v

Or, equivalently:

p' = 2p

Correct 2) 2p
