IMPULSE AND MOMENTUM

1. Which has more momentum, a heavy truck moving a t 30 km/h or a light truck moving at 30 km/h?

          

• heavy truck      

• light truck

• both have the same momentum

• cannot be determined

Based on the force equation, what will happen to the impact force when the time of impact increases?

           

• Force of impact remains the same

• There will be no changes on the force

• Force of impact will decrease

• Force of impact will also increase.

The impulse experienced by a body is equal to a change in its

          

• velocity   

• kinetic energy

• momentum   

• potential energy

When does a body with a momentum experience impulse?

     

 

• through velocity      

• through acceleration

• through motion      

• through collision

“Momentum demands movement.” What does this quote imply?

• You need to stop to maintain momentum.

• You need to push off others to gain your own momentum

• You need to set your goals and let others work for you.

• Keep moving ahead because action creates momentum.
