Is negative momentum possible?

Momentum can be negative. Momentum is a vector quantity, meaning it has both magnitude and direction.

Is negative momentum equal to positive momentum?

Momentum is a vector quantity, which means that it has direction. Momentum is always in the direction of the velocity. So if a body is moving in a direction with a positive velocity, the momentum will come out as positive. But if the velocity is negative, momentum will also be negative.

Can you have negative angular momentum?

We call this quantity angular momentum. The symbol ± indicates that angular momentum has a positive or negative sign to represent the direction of rotation; for example, in a given problem, we could choose to represent clockwise angular momenta as positive numbers, and counterclockwise ones as negative.

Is final momentum negative?

Correct answer: The initial momentum is positive because the problem states that the ball was originally thrown in the positive direction. The final momentum is negative due to the change in direction.

How do you add positive and negative momentum?

Positive momentum is built on the positive sales-related actions that propel your results forward. Negative momentum is built by taking non-sales related actions that cause a downward spiral of poor results—and a poor future.

Can you have negative impulse?

Impulse is a vector, so a negative impulse means the net force is in the negative direction. Likewise, a positive impulse means the net force is in the positive direction.

Can an impulse be negative?

Impulse is a change in momentum. A negative change in momentum is a negative impulse. There is nothing especially significant about this result. Like all vectors, by reversing your choice for the positive and negative directions of the coordinate axes, you could reverse the sign on the impulse.

Does friction do negative work?

The force of friction opposes the displacement (always), and does negative work.

Does gravity do negative work?

Gravity does negative work here because gravity goes in the opposite direction as the displacement.

Is it possible for momentum to be negative?

Momentum is a vector, meaning it has direction. Automatically things that are vectors CAN be negative. Take for example velocity or speed. If walking forward is positive then walking backwards is negative. If pushing forward means you’ve got positive momentum, then striding backwards would mean you have negative momentum. =)

How does momentum cancel each other out?

The object moving off to the left has a negative momentum, while the object moving to the right has a positive momentum. These two momenta are equal and opposite, so, when they are added together to calculate the total momentum afterwards, they cancel each other.

Why is momentum negative in an inelastic force?

After a collision (given that it is inelastic), however, the object most likely will move in the opposite direction, in which case the velocity is considered to be negative, which in turn makes the momentum negative.

What is the relationship between momentum and velocity?

As the velocity of a body approaches the speed of light, its momentum increases according to classical momentum equation p = mv. However, classical momentum theory becomes inconsistent with experimental results when a body is travelling at a relativistic velocity. This is because an object’s mass increases along with its velocity.
