driving force that keeps progress going
The force or energy that makes a plan, event, or group keep going and grow stronger or faster.
الگوی کاربرد:
the momentum of [a process/activity]
اشتباه رایج:
Learners sometimes confuse "momentum" with "moment". "Moment" is a short period of time, while "momentum" is the force that keeps something developing or moving. Many also try to make a plural (*momentums*) for this sense; in this meaning it is almost always used as an uncountable noun (e.g. "a lot of momentum", not *"many momentums").
هممعنیها
drive (Suggests strong energy and determination, especially in people or organizations.)

impetus (A more formal word for a force or event that causes something to start or to grow faster.)
متضادها
stagnation (Describes a situation where there is no growth or movement, the opposite of building momentum.)

اسم

2
force of a moving object
The power of movement that a moving thing has because it is heavy and fast, which makes it hard to stop.
الگوی کاربرد:
the momentum of [a moving object/body]
اشتباه رایج:
Learners often mix up "momentum" with "speed". Speed is how fast something moves; momentum also includes how heavy it is and suggests how hard it is to stop. Another mistake is using it with an article like a countable noun (*"a momentum"*); in this sense, it is normally uncountable ("a lot of momentum", "no momentum").
هممعنیها
impetus (Can refer to the push or force behind physical movement, slightly more formal.)
متضادها
standstill (Describes a state where something is no longer moving at all, the opposite of having momentum.)

physics: mass times velocity
In physics, a measure of motion that you get when you multiply how heavy something is by how fast and in what direction it is moving.
الگوی کاربرد:
the momentum of [an object/particle/system]
اشتباه رایج:
Students sometimes confuse momentum with force. Force changes an object’s momentum, but they are different quantities. Another common mistake is forgetting that momentum has direction (it is a vector), not just size.
هممعنیها
linear momentum (A more specific technical term for momentum in a straight line, used to distinguish it from angular momentum.)
متضادها
rest (In physics, an object at rest has zero momentum, so rest contrasts with having nonzero momentum.)
