AP Physics 1- Momentum, Impulse, and Collisions Practice Problems ANSWERS FACT: The product of mass and velocity is a vector quantity known as momentum ( ⃗). The equation for linear momentum is ⃗=𝑚𝑣⃗ and has the units kg· 𝑚 , which can also be written as a newton-second (N·s). Now take Newton’s second law 𝐹⃗ net
a) What was the initial momentum of the object? b) What was the final momentum of the object? c) What was the change in momentum? d) What was the impulse? 14) A 3 kg soccer ball is accelerated from rest to a speed of 15 m/s in a time of 0.40 s. a) What was the soccer ball’s change in momentum?
• Understanding how to connect principles of physics (torque, angular momentum, and impulse) to observed behavior of a physical system. • The ability to derive a relationship using conservation of angular momentum.
3 wrz 2024 · When momentum varies with time, the net external force exerted on the system can be found from the slope of the momentum-time graph. A force-time graph can be translated into a momentum-time graph, and vice versa, by applying the relationship between force and momentum.
