Impulse

What is the definition of impulse?

• The distance an object travels

• The speed of an object

• The change in momentum of an object

• The force of gravity on an object

How is impulse calculated?

• Force multiplied by time

• Mass multiplied by acceleration

• Velocity divided by time

• Work divided by distance

What are the units of impulse?

• Joules

• N

• kg m/s

• m/s^2

Explain the concept of impulse in terms of Newton's second law of motion.

• Impulse is the same as momentum

• Impulse is not related to force or time

• Impulse is the product of mass and acceleration

• Impulse is the change in momentum of an object, and it is equal to the force applied to the object multiplied by the time over which the force is applied.

How does impulse relate to the force acting on an object?

• Impulse is inversely related to the force acting on an object

• Impulse is only related to the mass of the object

• Impulse is directly related to the force acting on an object.

• Impulse is unrelated to the force acting on an object

Explain the difference between impulse and momentum.

• Impulse and momentum are the same thing.

• Impulse is the change in momentum of an object, while momentum is the product of an object's mass and its velocity.

• Impulse is the product of an object's mass and its velocity, while momentum is the change in momentum of an object.

• Impulse is the force applied to an object, while momentum is the speed of the object.

What happens to the impulse if the force applied on an object is doubled?

• The impulse remains the same

• The impulse is halved

• The impulse is doubled

• The impulse is quadrupled

How does the duration of force application affect the impulse on an object?

• The longer the duration, the lesser the impulse

• The duration does not affect the impulse

• The shorter the duration, the greater the impulse

• The longer the duration, the greater the impulse
