Momentum is defined as the product of an object's mass and velocity. It is a vector quantity, which means that it has both magnitude and direction. The formula for momentum is:
p = mv
Where:
p = momentum
m = mass of the object
v = velocity of the object
Here are five situational examples of momentum, along with their solutions using the momentum formula:
1. A 5-kg ball is thrown with a velocity of 10 m/s. What is its momentum?
p = mv
p = 5 kg x 10 m/s
p = 50 kg m/s
2. A car with a mass of 1000 kg is moving at a velocity of 20 m/s. What is its momentum?
p = mv
p = 1000 kg x 20 m/s
p = 20,000 kg m/s
3. A bullet with a mass of 0.01 kg is traveling at a velocity of 300 m/s. What is its momentum?
p = mv
p = 0.01 kg x 300 m/s
p = 3 kg m/s
4. A truck with a mass of 5000 kg is moving at a velocity of 15 m/s. What is its momentum?
p = mv
p = 5000 kg x 15 m/s
p = 75,000 kg m/s
5. An airplane with a mass of 10,000 kg is flying at a velocity of 300 m/s. What is its momentum?
