Question

when options are true about momentum​

Answer 1

Answer:

Explanation:

Momentum is a vector quantity. Like all vector quantities, the momentum of an object is not fully described until the direction of the momentum is .identified

one should be quick to note that the object does not have to have a constant speed in order to have momentum.

Momentum is calculated as the product of mass and velocity. As the speed of an object increases, so does its velocity.

For the same speed (and thus velocity), a more massive object has a greater product of mass and velocity; it therefore has more momentum.

Objects with a changing speed also have a changing velocity. As such, an object with a changing speed also has a changing momentum.

Answer 2

Answer:

a) Momentum is a vector quantity

b) The Unit of Momentum is kg m/s

d) When two bodies acts on each other and no external force is acting on the system, then the momentum remains constant
