The momentum of an object is in the same direction as its ____
A
force
B
velocity
C
acceleration
D
inertia
Explanation: 

Detailed explanation-1: -Linear momentum is a vector quantity defined as the product of an object’s mass, m, and its velocity, v. Linear momentum is denoted by the letter p and is called momentum for short: Note that a body’s momentum is always in the same direction as its velocity vector. .

Detailed explanation-2: -Please note that the body’s momentum is always in the same direction as its velocity vector. It’s a conserved quantity which means that the total momentum of a system is constant. The unit of linear momentum is kg m / s .

Detailed explanation-3: -Note:Momentum is not always only dependent on the mass and speed of the target.In a particularly given direction, velocity is distance, so an object’s momentum, therefore, depends on the direction of motion.It refers that an object’s velocity will shift whether the object accelerates or slows down.

Detailed explanation-4: -Answer and Explanation: The momentum of an object is the product of its mass and velocity. Therefore is two objects have the same velocity but difference masses, there momentum will not be the same.
