Lesson: Momentum High School PhysicsPhysics
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.
Sample Question Videos
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?
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?
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?
