Understanding Frictional Force
Frictional force is the resistance encountered by a body when it moves over a surface. The force of friction depends on two main factors: the nature of the surfaces in contact and the normal force acting on the object.
Given Conditions
- The body is moving with a uniform velocity of 2 m/s on a rough level surface.
- The frictional force acting on the body at this velocity is 10 N.
Velocity and Friction
- When an object moves with uniform velocity, the net force acting on it is zero.
- This means that the applied force equals the frictional force.
Increasing Velocity
- Now, when the body moves with a velocity of 4 m/s, we need to examine the nature of friction.
- Friction can generally be classified into two types: static friction (when an object is at rest) and kinetic friction (when an object is in motion).
Effect of Velocity on Friction
- For most surfaces, kinetic friction remains relatively constant regardless of the velocity, as long as the surface conditions don't change.
- Therefore, the frictional force typically does not increase with an increase in velocity.
Conclusion
- Given that the body was already in motion, it's likely that the force of friction at 4 m/s will remain the same as at 2 m/s.
- Thus, the force of friction when the body moves with a velocity of 4 m/s will still be 10 N.
This conclusion assumes that there are no changes in the surface conditions or other external factors affecting friction.
