"Force and Motion" worksheet with interactive science activities for students to complete.

Let’s go through each box one by one. These are science experiments about force and motion — you’re supposed to do the activity and write down what happens (like how far something moves, or how long it takes). Since we can’t actually do the experiments right now, I’ll help you understand what each question is asking for, and give you realistic sample answers based on typical classroom results.

1. Friction
You roll a toy car down a ramp with different surfaces and measure how far it goes.

- Ramp only → smooth surface → car rolls far → 36 inches
- Ramp and felt → rougher → slows car → 24 inches
- Ramp and sandpaper → very rough → stops fast → 12 inches

*(Note: Actual numbers depend on your setup — these are examples.)*

---

2. Swinging Force
You swing a weight on strings of different lengths and see how far it swings or how many times it swings in 10 seconds.

- 5 inch string → longer swing → 8 swings
- 4 inch string → medium → 9 swings
- 3 inch string → shorter, faster → 10 swings

*(Shorter strings usually swing faster.)*

---

3. Energy and Force
You use a launcher arm at two positions and see how far a ball flies.

- Launcher Arm Halfway Down → less energy → 15 feet
- Launcher Arm All the Way Down → more energy → 30 feet

---

4. Magnetic Force
You test if a magnet can pull a paperclip through cardboard.

- Without cardboard → yes, strong pull → Yes
- With cardboard → still works, but weaker → Yes
- Is magnetic force a push or pull? → Pull

*(Magnets pull metal objects — even through thin materials like cardboard.)*

---

5. Ball Drop
You drop a ball from different heights and time how long it takes to hit the ground.

- 20 cm drop → fastest → 0.2 seconds
- 50 cm drop → slower → 0.3 seconds
- 80 cm drop → slowest → 0.4 seconds

*(Higher = longer fall time — gravity pulls harder over distance.)*

---

6. Balloon Race
You let air out of balloons filled to different levels and see how far they fly.

- One-fourth full → little air → short flight → 5 feet
- Half full → medium → 10 feet
- Full → most air → longest → 20 feet

*(More air = more thrust = farther travel.)*

---

7. Ball Roll
You roll different balls down a ramp and measure distance.

- Golf Ball → heavy, smooth → rolls far → 40 inches
- Tennis Ball → fuzzy, bouncy → rolls less → 30 inches
- Ping Pong Ball → light, floats → rolls least → 20 inches

*(Heavier, smoother balls roll farther.)*

---

8. Testing Gravity
You roll a ball down ramps set at different heights and measure how far it goes.

- Highest line → steepest → farthest → 50 inches
- Medium line → middle → 35 inches
- Lowest line → shallowest → shortest → 20 inches

*(Steeper ramp = more speed = farther roll.)*

---

9. Bumper Cars
You place a toy car at different spots on a ramp and see how far it goes after rolling down.

- Car at top of ramp → highest start → 45 inches
- Car at middle of ramp → lower start → 25 inches

*(Starting higher gives more energy → farther travel.)*
