On the graph of velocity vs. time, Δv/Δt is the slope of the curve. If the curve is straight, the acceleration is constant. If the curve isn't straight we have to do the same trick we did before with ...

Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact. The gradient of speed-time and velocity-time graphs represent acceleration.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The questions in this quiz are suitable for GCSE physics students studying motion in a straight line, velocity and acceleration, distance-time graphs, velocity-time graphs and velocity ...

Instantaneous Velocity. Instantaneous velocity is defined as the limit of the average velocity as the time interval Δt becomes infinitesimally small. Its dimensions are [M 0 L 1 T-1] and its S.I ...

Different types of velocity are explored, and we investigate how to find information from a position versus time graph. ... Physics in Motion. Unit 2 Segment B: Speed and Velocity.

Position- time graph. Speed and velocity: ... Escape velocity, motion of a satellite, orbital velocity, time period and energy of satellite. UNIT 7: PROPERTIES OF SOLIDS AND LIQUIDS.
