- You only need to calculate the magnitude of the resultant force.
- You don't need to calculate the resultant force.
- You only need to calculate the direction of the resultant force.
- You need to calculate both the magnitude and direction of the resultant force. (correct)
What is the resultant force when two forces of 20 N and 10 N act in the same direction?
What is the resultant force when two forces of 20 N and 10 N act in the same direction?
- $\text{Resultant force} = 20 \, \text{N}$
- $\text{Resultant force} = 30 \, \text{N}$ (correct)
- $\text{Resultant force} = 10 \, \text{N}$
- $\text{Resultant force} = 50 \, \text{N}$

Study Notes
Calculating Resultant Force
- To calculate the resultant force, you need to add the individual forces acting in the same direction.
- When two forces act in the same direction, the resultant force is the sum of the individual forces.
Resultant Force and Direction
- When two forces of 20 N and 10 N act in the same direction, the resultant force is 30 N (20 N + 10 N).
- The direction of the resultant force is the same as the direction of the individual forces, since they are acting in the same direction.
