Grade 9 forces worksheets
Skills covered
- Net force
- Balanced vs unbalanced
- F = ma with one unknown
- A friction or gravity word problem
Sample questions and answer key
1. A 5 kg cart is pushed with 20 N. Ignore friction. What is the acceleration?
Answer: a = F/m = 20/5 = 4 m/s²
2. Two people push a box right with 30 N and left with 10 N. What is the net force?
Answer: 20 N to the right.
3. If forces on an object are balanced, what is true of its velocity?
Answer: Velocity is constant (including staying at rest).
Teaching notes
Require a free-body sketch on every word problem. Grade 9 should show arrows before they plug into F = ma.
