Question

Two particles of different mass start from rest. The same net force acts on both of them as they move over equal distances. How do the magnitudes of their final momenta compare? (a) The particle of larger mass has more momentum. (b) The particle of smaller mass has more momentum. (c) The particles have equal momenta. (d) Either particle might have more momentum.

Answer 1

Option a.The particle of larger mass has more momentum.

How this is explained?

• Given two particles are of different mass & start from rest .
• They have same net force & distance travelled due to force is also constant.
• We know Kinetic energy
• $KE=1/2mv^{2}$ and momentum p = mv .
• The same gives larger mass a smaller acceleration.
• The body which has larger mass will take a longer time interwal to move through same distance; the impulse given to larger mass is larger, thus larger mass will have a greater final momentum.
• Thus option(a).

What is a momentum?

• In Newtonian mechanics, linear momentum, translational momentum, or simply momentum is the product of the mass and velocity of an object.
• It is a vector quantity, possessing a magnitude and a direction.
• If m is an object's mass and v is its velocity (also a vector quantity), then the object's momentum p is :p=mv.
• In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second.
