  • The kinematic equations (article) | Khan Academy
    The kinematic equations are only accurate if acceleration is constant during the time interval considered So, we can only use them when the acceleration is not changing A fourth equation can be useful when acceleration is known to be constant, but its value is unknown This equation can be derived by combining two equations for average velocity
  • Projectile motion (article) | Kinematics | Khan Academy
    Projectile motion and the kinematic equations A projectile’s acceleration is constant So, we can analyze its motion using the kinematic equations for motion with constant acceleration
  • Motion with constant acceleration review - Khan Academy
    Review the key concepts, equations, and skills for motion with constant acceleration, including how to choose the best kinematic formula for a problem
  • Acceleration: At a glance (article) | Khan Academy
    We can describe acceleration as the change in velocity over time, and we can use the shorthand equation a = Δ v Δ t to represent this relationship where ‘a’ is the average acceleration, ‘v’ is velocity, and ‘t’ is time The Δ is a Greek symbol that means “change”
  • The kinematic equations (article) | Khan Academy
    What is a free falling object (a projectile)? It might seem like the fact that the kinematic equations only work for time intervals of constant acceleration would severely limit the applicability of these equations However one of the most common forms of motion, free fall, just happens to be constant acceleration
  • Free fall (article) | Kinematics | Khan Academy
    Since the kinematic equations apply to scenarios involving uniform acceleration, we can conclude that the ball fell with uniform acceleration Many similar experiments have reproduced the same result: The acceleration of a free-falling object near Earth's surface is uniform (constant)
  • Kinematics | AP®︎ College Physics 1 | Science | Khan Academy
    Explore the fundamentals of motion by analyzing and applying multiple representations to interpret and model the movement of objects Build proficiency in using words, diagrams, graphs, and mathematical models to understand objects undergoing constant acceleration Challenge common misconceptions and expand mathematical reasoning in the context of kinematics
  • Uniform circular motion and centripetal acceleration review
    Review the key concepts, equations, and skills for uniform circular motion, including centripetal acceleration and the difference between linear and angular velocity
  • Centripetal acceleration review (article) | Khan Academy
    Review the key concepts, equations, and skills for centripetal motion, including intuition for the direction of centripetal acceleration
  • Developing kinematic equations from data - Khan Academy
    Experimental data for an object moving with constant acceleration can be used to develop the kinematic equations See how this can be accomplished using a process called linearization
