1Question

What is a force?

2Question

Name one force that can make a robot move.

3Question

What do we call the force that pulls objects toward Earth?

4Question

If you push a toy robot forward, which way does the force act?

5Question

What happens to a robot if the forces on it are balanced?

6Question

What happens to a robot if the forces on it are unbalanced?

7Question

A robot is not moving. You apply a force to it. What might happen?

8Question

A robot is moving straight ahead. You push harder in the same direction. What happens to its speed?

9Question

A robot rolls across a carpet. What force makes it harder to move?

10Question

Why does friction matter in robotics?

11Question

What is one way to reduce friction on a robot?

12Question

What is one way to increase friction on a robot?

13Question

A robot arm lifts a box. What force must it use against gravity?

14Question

If two people pull a robot in opposite directions with equal force, what happens?

15Question

A robot’s motor turns the wheels. What kind of force is the motor creating?

16Question

A robot slows down when it hits a thick rug. Which force is increasing?

17Question

A robot starts turning left. What does that tell you about the forces on it?

18Question

Why do some robots have larger wheels for moving over bumps?

19Question

If a robot is on a ramp, what force pulls it downward along the ramp?

20Question

How can a ramp help a robot lift an object with less force?

21Question

A robot vacuum uses sensors to stop before it bumps into a wall. How does this help with forces?

22Question

A robot needs to push a heavy box. What change might help it move the box more easily?

23Question

Why might a robot need more force to move on sand than on a smooth floor?

24Question

A robot arm can pick up a small cup but not a heavy book. What does this show about force?

25Question

A robot changes speed from slow to fast after being programmed to do so. Is this caused by balanced or unbalanced forces?

26Question

Design question: If you wanted a robot to move smoothly across a classroom floor, what two things could help?

27Question

A robot must stop quickly. What force helps the robot stop?

28Question

Why do robot grippers often have rubber pads?

29Question

Explain how forces affect a robot in one full sentence.

30Question

Challenge: A robot is moving forward, but its left wheel gets stuck. What may happen to the robot’s motion, and why?

Answer Key

#	Answer
1	A force is a push or a pull on an object.
2	A push or a pull.
3	Gravity.
4	Forward, in the direction of the push.
5	It stays still or keeps moving at the same speed in the same direction.
6	Its motion changes. It may speed up, slow down, or change direction.
7	It may start moving.
8	It increases, so the robot speeds up.
9	Friction.
10	Friction can slow a robot down or help its wheels grip the ground.
11	Use smooth wheels, lubrication, or smoother surfaces.
12	Use grippy tires or rougher surfaces.
13	An upward force or lifting force.
14	The forces are balanced, so the robot does not move or does not change motion.
15	A pushing force through the wheels that helps the robot move.
16	Friction.
17	The forces are unbalanced and causing a change in direction.
18	Larger wheels can roll over obstacles more easily and need less force to get over bumps.
19	Gravity.
20	It spreads the lift over a longer distance, so less force is needed at one time.
21	It prevents a collision force from acting on the robot.
22	Use stronger motors or add wheels to reduce friction.
23	Sand creates more friction and resists movement.
24	The arm does not have enough force for the heavier object.
25	Unbalanced forces.
26	Smooth wheels and reduced friction, or a flat surface and a strong motor.
27	Friction.
28	Rubber pads increase friction and help the robot hold objects better.
29	Forces can start, stop, speed up, slow down, or change the direction of a robot.
30	The robot may turn, slow down, or stop because the forces on the two sides are no longer balanced.
