Grade 11 Science Worksheet

Circle the best answer, or write your answer on the line.

  1. A ball rolls off a table 0.784 m high. With g = 9.8 m/s² and no air, how long does it take to land, Ari?

  2. A ball rolls off a table 1.225 m high. With g = 9.8 m/s² and no air, how long does it take to land, Bo?

  3. A ball rolls off a table 0.441 m high. With g = 9.8 m/s² and no air, how long does it take to land, Esme?

  4. Read this first

    Trajectory grid (computed values, g = 9.8 m/s²)

    Distance from the table (m) across, 0 to 1.6, a mark every 0.2 m; drop below the table top (m) down, 0 to 1.4, a mark every 0.2 m. The ball leaves the table edge at 3 m/s. Points every 0.1 s: (0 m, 0 m), (0.3 m, 0.049 m), (0.6 m, 0.196 m), (0.9 m, 0.441 m), (1.2 m, 0.784 m), (1.5 m, 1.225 m). At each point a horizontal arrow shows 3 m/s, and a downward arrow shows 0, 0.98, 1.96, 2.94, 3.92, 4.9 m/s.

  5. In the trajectory grid, how long after leaving the table does the ball land, Jun?

    • 0.25 s
    • 1.5 s
    • 0.5 s
    • 1.225 s

  6. In the trajectory grid, how far from the table does the ball land, Kira?

    • 3 m
    • 1.5 m
    • 0.3 m
    • 1.225 m

  7. In the trajectory grid, how fast is the ball moving downward as it lands, Luz?

    • 3 m/s
    • 4.9 m/s
    • 9.8 m/s
    • 0 m/s

  8. Two balls roll off the same table at 1 m/s and 3 m/s. How do their landings compare, Milo?

    • Same place, same time
    • Same time; the faster lands farther
    • The faster one lands sooner
    • The faster one lands later

  9. A spring toy fires a ball sideways off a table as a second ball drops from the same height. Which lands first, Noah?

    • They land together
    • Whichever is heavier
    • The dropped ball; the fired one stays up longer
    • The fired ball

  10. Pia doubles the speed of a ball rolling off the same table. What happens to the landing distance?

    • It stays the same
    • It becomes four times as far
    • It doubles
    • It halves

  11. A ball leaves a table at 3 m/s. With no air, what is its sideways speed as it lands, Zee?

    • 0 m/s
    • 3 m/s
    • 1.5 m/s
    • 4.9 m/s

About this worksheet

Objects launched sideways. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can explain that sideways and downward motion are independent, with no air:
  • I can find the fall time from the height (t = √(2h ÷ g)), then the landing distance (x = vt), and work backward to a launch speed.
  • I can combine sideways and downward speeds at landing as a right triangle.
  • I can predict a drone drop: the ball stays below a steadily moving drone. I can reject the cartoon path (straight out, then straight down) and the idea of a forward force.

Standard: supports HS-PS2-1

Words to know

projectile: An object moving through the air under gravity alone

trajectory: The path a projectile follows

horizontal: Sideways, parallel to the ground

independent: One direction's motion doesn't change the other's

range: How far sideways a projectile lands from its start

Common mistakes

Your child divided speed by time. Sideways distance is sideways speed × time, because nothing slows the ball sideways.

Your child stopped before the square root. From h = ½gt², 2h ÷ g gives t², so take the square root.

Your child thought the sideways speed fades. With no air, nothing pushes the ball sideways, so its sideways speed stays the same.

Questions parents ask

What is the most common mistake with objects launched sideways?

Your child divided speed by time. Sideways distance is sideways speed × time, because nothing slows the ball sideways.
