Average speed equals total distance divided by total time. Formula: s = d/t, where d is distance and t is time. Result shows speed per unit of time, usually in meters per second
Newton's second law is incorrect in F=ma form. Law should be written as vectorial F=m*a or momentum F=dp/dt. Second law connects environmental force with body's motion change. Law only measures force outcome, not force itself
Newton's first law states that an object remains at rest or moves at constant velocity unless acted upon by a net external force. Friction is an external force that causes objects to slow down. The law applies to all physical processes involving force and motion
Newton's three laws describe the relationship between motion and forces. First law states that objects remain at rest or move at constant speed unless acted upon by force. Second law relates force to momentum change: force equals mass times velocity derivative. Third law states that forces between interacting bodies have equal magnitude but opposite directions
Newton (N) is the SI unit of force. One newton equals 1 kg⋅m/s² acceleration of 1 kg at 1 m/s². Named after Isaac Newton for his second law of motion. Standardized in 1946 by CGPM Resolution 2
Acceleration is the rate of change of velocity with respect to time. Acceleration is a vector quantity with magnitude and direction. SI unit is metre per second squared (m⋅s−2)
