Unit 5: Projectile Motion

Question 1

projectile motion

Answer 1

motion of an object projected by some means and keeps going due to:

• inertia (not a force)
• gravity (F(g))

Question 2

What is projectile motion?

Answer 2

Motion of an object projected by some means and keeps going due to:

• inertia (not a force).
• gravity (Fg).

Question 3

What forces act on a body in projectile motion?

Answer 3

Only gravity (ignoring air resistance).

Question 4

Describe the changes in the vertical component of the velocity of a projectile.

Answer 4

It increases by 10 m/s/s.

Question 5

Describe the changes in the horizontal component of the velocity of a projectile.

Answer 5

It remains constant.

Question 6

What impact does the vertical velocity have on horizontal velocity component?

Answer 6

There is no impact.

Question 7

Ignoring air resistance, if you fire a bullet (aimed horizontally) from a gun and drop a bullet from the same height, which will hit the ground first? Why?

Answer 7

Neither, they will hit the ground at the same time, because

Question 8

What projection angle will give the maximum range?

Answer 8

45º

Question 9

What is the relationship between the range of a projectile and the projection range?

Answer 9

It adds up to 90º.
