Momentum

1. During a family outing at the bowling alley, Jomar rolls an 8-kilogram bowling ball straight down the lane. The ball travels at a speed of 2 meters per second as it heads toward the pins. What is the momentum of the bowling ball as it rolls down the lane?

Back

Given:

Mass (m) = 8 kg

Velocity (v) = 2 m/s

Momentum (p) = ?

Solution:

p = m × v

p =8 kg×2 m/s

p =16 kg-m/s

2. A cyclist and her bike have a total mass of 75 kilograms. They are moving in a straight line at a velocity of 6 meters per second. What is their momentum?

Back

Given:

Mass (m) = 75 kg

Velocity (v) = 6 m/s

Momentum (p) =?

 

Solution:

p = m × v

p = 75 kg×6 m/s

       p = 450 kg-m/s

Based on what you observed and solved today, how do mass and velocity work together to affect an object’s momentum?

Back

Mass and velocity work together because momentum depends on both. If an object has more mass or moves faster, it has more momentum.

Front

Can two objects with different masses have the same momentum? Why or why not?

Back

Yes, two objects with different masses can have the same momentum. If the object with the smaller mass moves faster and the object with the bigger mass moves slower, their momentum can be equal because momentum depends on both mass and velocity.

Why is momentum important to understand in real-life situations like driving, sports, or collisions?

Back

Momentum is important because it helps us understand how things move and how hard they are to stop.
