Question 5
Question
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..
Answer
True
False
Question 6
Question
When a ball falls from the roof of a building, it accelerates until it stops accelerating. Why?
Answer
It hit the ground
it reached its terminal velocity
projectile motion
gravity stopped
Question 7
Question
Why does a projectile follow a curved path?
Answer
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
