In this lesson, we will learn how to use the formula for momentum, p = mv, to calculate the momentum of objects and calculate changes in an object’s momentum.
Students will be able to
Q1:
A cricket ball of mass 160 g has a constant velocity of 10 m/s. A golf ball of mass 40 g has the same velocity as the cricket ball. What velocity change must the cricket ball undergo to have the same momentum as the golf ball?
Q2:
How many times greater is the momentum of a 1,500 kg mass hippo moving at 0.25 m/s than a 75 g mass bird flying at 10 m/s?
Q3:
A book falls off the edge of a table. The book accelerates at 9.8 m/s2 for 0.15 s and its momentum after falling for 0.15 s is 0.147 kg⋅m/s. What is the book’s mass in grams?
