2. force
3. motion
4. weight
5. pull
7. Resultant force is also known as the net force. In many situations, more than one force acts on a body at the same time. All these forces collectively produce the same effect in the body as a single force hence it is defined as the single force which acts on a body to produce the additive effect of all the forces that work on that object. If two forces acting on an object are in same direction; they are added. If two forces are in different directions then we subtract them.
8. Pressure = 35 N/7 m2
= 5 N/ m2
9. It is a pull force.( Contact force)
1. food
2. pascal
