Momentum is a physics concept that describes the quantity of motion of an object. It is calculated by multiplying an object's mass by its velocity.
When velocity is doubled, momentum is also doubled. This is because momentum is directly proportional to velocity. As velocity increases, so does the object's momentum.
Momentum and velocity have a direct relationship. As velocity increases, so does momentum. This means that if velocity is doubled, momentum is also doubled.
No, an object cannot have momentum without velocity. Momentum is dependent on an object's velocity, so if an object is not moving, it has no momentum. However, an object can have velocity without momentum if its mass is very small.
In a closed system, momentum is conserved, meaning that the total momentum of the system before and after a collision remains the same. This is known as the law of conservation of momentum and is an important principle in physics.
