Study Notes
Momentum and Impulse
- Momentum is defined as inertia in motion
- It's a vector quantity
- Momentum can be calculated as p = mv, where:
- p = momentum
- m = mass
- v = velocity
- Momentum is expressed in units of kg • m/s (kilogram-meters per second)
- The greater the mass or velocity of an object, the greater its momentum
- A stationary object has zero momentum
Impulse
- Impulse is defined as the product of force and time (I = Ft)
- I = impulse
- F = force
- t = time
- Impulse is expressed in units of Newton-seconds (N • s)
- Impulse changes momentum (Ft = Δp)
Balat Sibuyas Activity
- Students sing the school hymn while passing a "sibuyas" (onion)
- The student holding the "sibuyas" when the song stops answers the question in the current layer they are peeling.
- Cycle repeats until all questions are answered.
Objectives
- Relate impulse and momentum to collisions of objects
- Derive the equation of impulse from the law of acceleration
Challenge Question: Basketball Dunk
- To dunk a basketball, the player needs to propel themselves to a certain height
- Impulse and momentum can be used to increase the chance of reaching the rim
- The player can increase the time over which the impulse acts on them to reduce the force needed to reach the rim and dunk the basketball
Practice Drill
- Conduct a short practice to solve problems with questions for practice, recording and review for areas of improvement
