Help interpreting a momentum graph

In summary, a momentum graph is a visual representation of an object's momentum over time, calculated by multiplying its mass by its velocity. To interpret a momentum graph, one should look at the slope, with a steeper slope indicating greater momentum and a flatter slope indicating lower momentum. Momentum is important in physics as it is a fundamental quantity that helps us understand the motion of objects and is conserved in all types of collisions. It is also related to force through Newton's second law of motion. Additionally, a momentum graph can provide information about the energy of an object through the area under the graph, which represents the impulse.

Homework Statement



What is the objects momentum at 3 seconds, on the graph at 3 seconds it is exerting 35n

Homework Equations



f=change in momentum/time

The Attempt at a Solution


I got 105kgms but it was marked wrong...
I can make the graph in paint if it will help anybody.

It would be beneficial to post the graph as well.

then simply the area under the graph gives the change in momentum, so from t=1 to t=3 find the area. It forms a rectangle and triangle.
 

1. What is a momentum graph?

A momentum graph is a visual representation of an object's momentum over time. Momentum is a measure of an object's motion and is calculated by multiplying its mass by its velocity.

2. How do I interpret a momentum graph?

To interpret a momentum graph, look at the slope of the graph. A steeper slope indicates a greater momentum, while a flatter slope indicates a lower momentum. Additionally, the direction of the slope can indicate the direction of the object's motion.

3. Why is momentum important in physics?

Momentum is important in physics because it is a fundamental quantity that helps us understand the motion of objects. It is conserved in all types of collisions and is a key factor in determining the outcome of a collision.

4. How is momentum related to force?

Momentum is related to force through Newton's second law of motion, which states that force is equal to the change in momentum over time. This means that the greater the force acting on an object, the greater the change in its momentum will be.

5. Can a momentum graph tell us about the energy of an object?

Yes, a momentum graph can provide information about the energy of an object. The area under the graph represents the impulse, which is equal to the change in momentum. Since energy is also conserved in collisions, the impulse can tell us about the energy transfer between objects.
