Inclined plane and kinetic energy

Click For Summary
SUMMARY

The discussion focuses on the relationship between kinetic energy and gravitational potential energy when a block of mass m slides up an inclined plane to a height h without friction. The key principle is the conservation of energy, which states that the gravitational potential energy gained by the block equals its initial kinetic energy. The relevant equation is derived from the energy conservation principle, emphasizing that understanding the underlying physical concepts is crucial for applying the correct equations.

if a block of mass m is to slide up an inclined plane to at least a height of h (with no friction), what is the minimum kinetic energy it must have?

no numbers are included...just supposed to know an equation to get the answer.

Use energy Conservation!
Gravitational Potential energy gained= Initial Kinetic Energy
 
Equations are just "tools" of physics. More than "just knowing an equation" what physical concepts are involved here? That should help you think of an equation.
