Question

Answer in one sentence :
1.) A blacksmith hammers a hot piece of iron while making a tool. How does the force due to hammering affect the piece of iron?
3.) state two effects of force.
4.) what is force of friction?
​

Answer 1

Answer:

1. The force is applied due to hammering causes the change in shape of iron and iron can be moulded in the shape of the required tool.
2. A force acting on an object causes the object to change its shape or size, to start moving, to stop moving, to accelerate or decelerate. When there's the interaction between two objects they exert a force on each other, these exerted forces are equal in size but opposite in direction.
3. The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object.
