26 paź 2020 · Momentum Problems Problem (1): What is the definition of momentum in physics? Solution: the product of a particle's mass and velocity in physics is called the particle's momentum, $\vec{p}=m\vec{v}$. Momentum is a vector quantity like velocity, acceleration, and force. The units of momentum are kg.m/s. Practice Problem (2): If a truck has a ...
This collection of problem sets and problems target student ability to use momentum, impulse, and conservations principles to solve physics word problems associated with collisions, explosions, and explosive-like impulses.
Collision Analysis and Momentum Problems. Using Equations as Guides to Thinking. Momentum Conservation in Explosions. As discussed in a previous part of Lesson 2, total system momentum is conserved for collisions between objects in an isolated system. The momentum lost by one object is equal to the momentum gained by another object.
Linear momentum questions with solutions and explanations are presented. These questions may be used to practice for the SAT physics test. Questions. If the speed and mass of an object are doubled, which of the following is true? A) The momentum of the object is doubled. B) The kinetic energy of the object is doubled.
The diagrams below represent generic objects before a collision followed by a set of outcomes to be considered. Comment on the outcomes, paying attention to the energy and momentum before and after each collision.
Questions on Momentum. 1. A model truck A of mass 1.2 kg is travelling due west with a speed of 0.90 m s–1. A second truck B of mass 4.0 kg is travelling due east towards A with a speed of 0.35 m s–1. Calculate the magnitude of the total momentum of the trucks.
Impulse-Momentum: Determine the momentum of our spacecraft. What mass of interstellar medium is swept up during the journey? What impulse does the interstellar medium deliver to the spacecraft? How does this impulse compare to the momentum of the spacecraft? Work-Energy: Determine the kinetic energy of our spacecraft.
