Warm up the big ideas
Before you show what you know, let's warm up the big ideas about forces. This is practice — it is not marked.
Practice questions
Q1. Is each force a contact force or a force at a distance?
| Force | Contact or at a distance? |
|---|---|
| Friction | |
| Magnetism | |
| A push | |
| Gravity |
Q2. A box has two equal arrows pushing in opposite directions. Are the forces balanced or unbalanced? Does the box move?
Q3. True or false? Gravity only pulls things straight down. Explain your answer.
Q4. Draw arrows on this sled so the forces are unbalanced and it moves to the right. Remember: bigger arrow = bigger force.
