Upon completion of this unit, you should be able to:
- compute linear momentum and the components of momentum.
- relate impulse and momentum, and kinetic energy and momentum.
- explain the condition for the conservation of linear momentum and apply it to physical situations.
- describe the conditions on kinetic energy and momentum in elastic and inelastic collisions.
- explain the concept of the center of mass and compute its location for simple systems, and describe how the center of mass and center of gravity are related.
- apply the conservation of momentum in the explanation of jet propulsion and the operation of rockets.
- Linear Momentum Lab. – Using kinematic carts, students will quantitatively examine the changes in momentum that result from a collision between carts and from an “explosion” acting simultaneously on two carts.
- Collision Lab – Using a technique similar to the projectile motion lab, students will graphically record the motion of two balls that collide at an angle. By marking their projectile paths with carbon paper, students can measure both direction and horizontal velocity after the collision.
