Impulse
A force of 50 N acts on a body for 0.2 seconds. What is the impulse imparted to the body?
Select the correct option:
Solution
10 N·s
- Impulse Definition: Impulse (J) is the product of the average force and the time interval over which it acts.
- Formula: J=FΔt.
- Data Usage:
- Force F=50 N.
- Time Δt=0.2 s.
- Calculation: J=50×0.2=10 N·s.
- Physical Meaning: Impulse is equal to the change in momentum of the object (J=Δp).
