Projectile Motion Review (EOY REVIEW 4)

By KAILEY MARTIN

Multiple Choice

BELL RINGER: A ball rolls off a 1.2 m high table. Which variable tells you how long it takes to hit the floor?

• How fast its rolling horizontally

• The height of the table

• The weight of the ball

Projectile Motion Quick Facts
Write this down!

• Time to fall depends only on vertical motion: t=√(2h/g)

  • g=9.8 m/s²

• Horizontal velocity (v_x) is constant.

• Vertical velocity starts at zero for horizontal launches.

• To find horizontal velocity: v_x=d/t

• To maximize time in air, increase the angle of launch

• To maximize distance, you need to launch at 45°
