Answer 2

Answer:

The unit for momentum can be Newton-second (N -s).

Explanation:

Momentum:

• The relationship between a particle's mass and velocity is known as its momentum.
• Momentum is  a vector quantity, momentum includes both magnitude and direction.
• According to Isaac Newton's second equation of motion, the force applied on a particle is equal to the time rate of change of momentum.
• The unit of momentum is defined as the product of the units of mass and velocity.
• Mass is measured in the term of kg  
• Velocity is measured in the term of m/s

Types of momentum:

Momentum includes two types:

• Linear Momentum
• Angular Momentum

Linear momentum: An object moving with a velocity has an linear momentum

Angular momentum: A spinning of an object has an angular momentum.

Importance of momentum:

• The relationship between speed, mass and direction can be described by momentum.
• It also defines the force required to start and maintain motion in objects.
• If an object has enough momentum, it can exert a lot of force despite appearing to be little.
• It can also indicates how an object will move after colliding, both in terms of speed and direction.
