Question 5 of 10

1

When you are swimming, you push through the water, in other words you are applying force to the water, and the water is applying the same amount of force to you. This is an example of fluid friction..

Select one of the following:

  • True
  • False

Explanation

1

When a ball falls from the roof of a building, it accelerates until it stops accelerating. Why?

Select one of the following:

  • It hit the ground

  • it reached its terminal velocity

  • projectile motion

  • gravity stopped

Explanation

Question 7 of 10

1

Why does a projectile follow a curved path?

Select one or more of the following:

  • two balls fall with different acceleration

  • Gravity pulls the object down

  • the combination of a vi and downward velocity causes the ball to follow a curved path

Explanation

Question 8 of 10
