Detailed Solution
Download Solution PDFThe correct answer is Force, Kinetic friction and Static friction.
Key Points
- Force has the dimensions [MLT-2], which represents mass (M), length (L), and time (T).
- Kinetic friction and static friction are both types of forces and hence share the same dimensional formula [MLT-2].
- Force is a vector quantity that causes an object to undergo a change in speed, direction, or shape.
- Kinetic friction acts on moving objects, while static friction acts on objects at rest to prevent them from moving.
Additional Information
- Impulse
- Impulse is the product of force and the time over which it acts. Its dimensional formula is [MLT-1].
- It is a vector quantity and is equal to the change in momentum of an object.
- Momentum
- Momentum is the product of mass and velocity. Its dimensional formula is [MLT-1].
- It is a vector quantity and is conserved in isolated systems.
- Newton's Second Law of Motion
- States that the force acting on an object is equal to the mass of that object times its acceleration (F = ma).
- This law provides a quantitative description of the changes that a force can produce on the motion of a body.
- Friction
- Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
- It plays a crucial role in many everyday processes, such as walking, driving, and the operation of machinery.
