Displacement from time and velocity example Instantaneous speed and velocity Acceleration: At a glance Acceleration Airbus A380 take-off time Airbus A380 take-off distance Why distance is area …

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared …

Velocity describes how position changes; acceleration describes how velocity changes. Two layers of change!

Let's explore what acceleration is and how we calculate it. Created by Mahesh Shenoy.

Use a simulation to investigate the effects of balanced and unbalanced forces on an object's motion. Explore how an object's acceleration is affected by the net force acting on it and its mass.

If the speed of an object remains the same but it changes direction, then the object is accelerating. People sometimes forget that acceleration and velocity aren’t always in the same direction. When …

The net force that acts on an object in the radial direction is sometimes referred to as centripetal force. The acceleration that it causes, also in the radial direction, is called centripetal acceleration (a → c).

Review the key concepts, equations, and skills for uniform circular motion, including centripetal acceleration and the difference between linear and angular velocity.
