The word momentum means mass and velocity taken together.
Mass is an intrinsic basic physical quantity which tells us about the amount of matter contained in a body. It is a scalar quantity and it is measured in kilogram(Kg).
Velocity is the rate of change of displacement . It is defined as displacement per unit time. It is a vector quantity and measured in meter per second (m/s)
The product of mass and velocity is momentum. When a body possesses both mass and velocity we say that it has momentum. It is a vector quantity. Its unit is kg m/s
Mathematically we write momentum as,
P = mv
Mathematically we write momentum a
Where, P = momentum
m = mass
v= velocity.
When a force is applied on a body, it changes its momentum. The relationship between force and momentum is given by Newton's second law of motion which states that the rate of change of momentum is directly proportional to the force applied,
F = Δp /Δt
Where F= force
Δp = change in momentum
Δt = time taken for the change in momentum to occur.

Answer:
In my mind when I hear the word momentum it comes that it is the product of mass and velocity.
Continental Tropical
The Sun's heat is spread unevenly on Earth, and the atmosphere and oceans circulate and redistribute heat.
Answer:
pressure=force/area
Explanation:
pressure equal to force divided by area,the area is how far the object sunk into the ground
Answer: The correct answer is "inertia".
Explanation:
Inertia: It is the state of the object which resists any change in it.
Newton's first law is also called "Law of inertia".
If the object is travelling at constant velocity then it will remain travel at the constant velocity or if it is at rest then it will remain in resting position provided that it is acted upon by an external force.
If the external force is applied to an object then, the state of the object can be changed. Otherwise, it will remain in its state.
Therefore, the tendency for an object i motion to remain in motion is called inertia.
