Theorem: Work done = Change in kinetic energy W=ΔKE=1/2mv^2−1/2mu^2 Conservative Forces: Path-independent (e.g., gravity) Non-Conservative Forces: Path-dependent (e.g., friction)
Significant figures are digits in a number that contribute to its precision. Rules:· All non-zero digits are significant.· Zeros between non-zero digits are significant.· Leading zeros are no...
