Questions

1. Write a sentence to explain what a resultant force is.
2. Can you calculate the resultant of two forces that act in a straight line?
3. Draw a free body diagram of an accelerating aircraft on the runway.
4. Draw a free body diagram of a bike moving at constant speed along a road.
5. Draw a scale diagram of a 10 N force at an angle of 40 degrees to the horizontal.
6. Resolve this 10 N force into two components at right angles to each other.
7. Calculate the resultant force in this situation. Two forces act on an object, a 25 N force in the north direction, and 20 N force at 90o to the east.
