5.22: REVIEW WITH QUIZIZZ: IMPULSE: 30W 4D S2 22

What is the correct definition of impulse?

• The movement of an object when a force is applied to that object
• Change in momentum over time
• Change in force
• The measure of mass in motion

What is the unit for impulse?

• m/s^2
• Ft
• N*s
• kg/ms & Direction

What is the formula for impulse?

• i = Ft
• F = ma
• p = mv
• a^2+b^2=c^2

What three things can happen to an object in order to make it experience impulse?

• An increase in force, an increase in time, and a change in mass.
• An increase in force, an increase in time, and a decrease in mass.
• An object speeds up, slows down, or changes direction.
• The object changes its mass, there is a change in speed, and a change in direction.

What is the symbol for momentum change?

• i
• F
• Δp
• J

A 6 kg ball has encounters a force of 15 N in 2.0 seconds. What is the impulse of the object?

• 90 kg*m/s
• 30 N*s
• 12 kg*m/s
• 300 N*s

If an 80 kg object experiences 20 N of force in 4 seconds. What is the impulse of the object?

• 1,600 N*s
• 240 N*s
• 320 N*s
• 80 N*s
