Understanding Impulse and Momentum

What is the unit of impulse?

• Kilograms

• Newton seconds

• Newton per second

• Joules

Which symbol is officially used to represent impulse?

• F

• P

• J

• I

How are impulse and momentum related according to Newton's second law?

• Impulse equals mass times velocity

• Impulse equals force times distance

• Impulse equals mass times acceleration

• Impulse equals force times time

In the egg drop experiment, what was the main difference between the two eggs?

• The surface they landed on

• The height from which they were dropped

• The mass of the eggs

• The initial velocity of the eggs

What was the approximate speed of the eggs when they hit the ground?

• 12.25 meters per second

• 9.25 meters per second

• 6.25 meters per second

• 3.25 meters per second

Why did the egg that landed on foam not break?

• It experienced a smaller force over a longer time

• It had a smaller mass

• It had a higher initial velocity

• It was dropped from a lower height

How much force did the egg experience when it stopped in a thousandth of a second?

• 3.75 Newtons

• 37.5 Newtons

• 375 Newtons

• 3750 Newtons

What factor determines the difference in force experienced by the two eggs?

• The height from which they were dropped

• The time taken to stop

• The mass of the eggs

• The initial velocity

What is the relationship between force and time in the context of impulse?

• Force is inversely proportional to time

• Force is directly proportional to time

• Force is equal to time

• Force is independent of time

What must be applied over time to change an object's velocity?

• An unbalanced force

• A balanced force

• A constant mass

• A constant velocity
