The baseball forces the bat in one direction and the bat forces the ball in the opposite direction.

Example of direction force. Hence the force exerted by the player on the ball is definitely a dynamic force. This force is known as the force of friction. Hitting of the baseball.

An object acted upon by an unbalanced force changes speed and direction. There is no opposing force to stop the motion of the ball. The force resisting the motion is applied in the direction opposite to the direction of motion of the hands is called the frictional force and is responsible to generate heat energy.

For example- In a cricket match a bowler bowls the ball towards the batsman with some velocity u. In the example the direction and sense of the 100 lb force would be down and to the left or 240 degrees A 100 pound force is applied to the stone column in the diagram. The colum will experience this force at every point along the line of action of the force.

The second part of Newtons first law is sometimes forgotten you have to remember that it applies to bodies that are moving at a constant velocity not just those at rest. We encounter centripetal force in our daily lives but not very frequently like gravitational force or frictional force. So the force exerted by the wall on the ball changes its direction of motion.

Example of inertia of motion. Rock climbing makes use of a force of friction to. When the pointed tip of the screw is placed on the top of a rigid surface and a twist force is applied to rotate it in a particular direction it gets embedded inside the structure.

This car would never stop unless a force acts upon it. Examples would include any situation where we turn or swing any object or move in orbits around a center. Example of unbalanced force.
