### Forces smartboard exported

1. 1. Do forces need to be equal in magnitude and opposite in direction to be balanced? 20 N 20 N
2. 2. How can the forces on an object be balanced if their magnitudes are not equal? 20 N 20 N 10 N 10 N 20 N
3. 3. How can the forces on an object be balanced if they have equal magnitudes but directions that are not opposite? F = 20 N 20 N F = 20 N 20 N F = 20 N
4. 4. Are these forces balanced? 20 N 20 N 120 ° 120 ° 120 ° 20 N
5. 5. Which direction is this box moving?
6. 6. Calculate the force acting on this box. m = 5 kg a = 2 m/s2 F = ? = 10 N
7. 7. Calculate the acceleration of this box. m = 5 kg F = 20 N a = ? = 4 m/s2
8. 8. Calculate the mass of this box. F=5N a = 2 m/s2 m = ? = 2.5 kg
