- force
- force
- motion
- weight
- pull
- 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.
- Pressure = 35 N/7 m2
= 5 N/ m2 - It is a pull force.( Contact force)
- food
- pascal
