Detailed Solution
Download Solution PDFThe correct answer is option 4.
Key Points
- Impulse is defined as the product of force and the time interval during which the force acts.
- Impulse equals the change in momentum of an object, not the change in acceleration.
- The formula for impulse is \( J = F \cdot \Delta t \), where \( J \) is impulse, \( F \) is force, and \( \Delta t \) is the time interval.
- Impulse has the same units as momentum (kg·m/s) and is a vector quantity.
Additional Information
- Newton's Second Law of Motion:
- States that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).
- Direction of Force:
- Force is not always in the direction of motion; for example, friction acts opposite to the direction of motion.
- Situational Force:
- The force on a body at any given time is determined by the external conditions and interactions at the location of the body.
- Momentum:
- Momentum is the product of mass and velocity of an object (p = mv).
- Impulse and momentum are closely related; impulse results in a change in momentum.
