This Grade 3 Science worksheet focuses on how the size and direction of a force change an object's motion. Students investigate how bigger pushes create more speed or distance, and how opposite equal forces cancel out. Through nine fill-in sentences and a four-pair matching activity, Grade 3 learners connect force size and direction to real motion outcomes, deepening NGSS 3-PS2 understanding of everyday pushes.
Style:
Forces and Motion
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A bigger push makes an object move faster than a smaller push.
2. Two equal forces in opposite directions will cancel each other out.
3. The direction of a force tells which way an object will move.
4. A harder kick sends a ball a farther distance than a light tap.
5. When two kids push a wagon the same way, the forces add together.
6. If you push a toy car left and a friend pushes right with equal force, it stays still.
7. The size of a push affects how fast an object moves.
8. A gentle push on a swing makes it move slower than a hard push.
9. Forces have both size and direction in Grade 3 Science lessons.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Big push on a ball
→ Ball rolls far and fast
Ball rolls far and fast
Two equal opposite pushes
→ Object stays still balanced
Object stays still balanced
Two pushes in same direction
→ Forces add for bigger motion
Forces add for bigger motion
Small push on a wagon
→ Wagon moves slowly a short way
Wagon moves slowly a short way
