driving force that keeps progress going
The force or energy that makes a plan, event, or group keep going and grow stronger or faster.
Padrão de uso:
the momentum of [a process/activity]
Erro comum:
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").
Sinônimos
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.)
Antônimos
stagnation (Describes a situation where there is no growth or movement, the opposite of building momentum.)

Substantivo
C1
property
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.
Padrão de uso:
the momentum of [a moving object/body]
Erro comum:
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").
Sinônimos
impetus (Can refer to the push or force behind physical movement, slightly more formal.)
Antônimos
standstill (Describes a state where something is no longer moving at all, the opposite of having momentum.)

Exemplos

- She lost her momentum on the stairs and had to stop to catch her breath.
- The ball bounced off the wall and changed direction, but it kept most of its momentum.
Exemplos para estudantes

Substantivo

C1
quantity
3
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.
Padrão de uso:
the momentum of [an object/particle/system]
Erro comum:
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.
Sinônimos
linear momentum (A more specific technical term for momentum in a straight line, used to distinguish it from angular momentum.)
Antônimos
rest (In physics, an object at rest has zero momentum, so rest contrasts with having nonzero momentum.)
Colocações
linear momentum
|conservation of momentum
|angular momentum
|momentum transfer
|momentum equation
|momentum vector

Exemplos
- According to the principle of conservation of momentum, the total momentum of the system remains constant.
- The momentum of the particle is given by the equation p = mv.
- In the collision, momentum is transferred from the moving car to the stationary barrier.
- Angular momentum must also be conserved when the figure skater pulls in her arms.
- They calculated the electron’s momentum based on its measured velocity.
Exemplos para estudantes
- In this physics class, we learn that momentum equals mass times velocity.
- The total momentum before and after the crash stays the same.
