Romeo and Juliet

Forces and their motions Distance eon graphical records The speed of an prey is the outmatch travelled each s < the slope of the breeze on a hold sequence graph represents the speed. * If an purpose is stationary, the distinguish on a surpass time graph is horizontal. * if an object is zany at a eternal speed, the by- office on a distance time graph-time graph is a straight line that slopes upwards Speed in metres per certify, m/s = distance travelled in metres, m time taken in seconds, s fastness and acceleration f number is speed in a presumption direction acceleration is the change of focal ratio per second speedup- positive Deceleration - negative If the velocity of an object changes we enunciate that it accelerates.

Acceleration = V-U T Acceleration = V-U T Acceleration is measured in metres per second m/s2 v is the utmost velocity in metres per second m/s u is the initial velocity in metres pe r second, m/s t is the time taken for the ! change in seconds, s Velocity time graphs * If the line on a velocity time graph was horizontal, the acceleration is zero. This means the object is travelling at a steady speed/ constant velocity. * The slope of a velocity time graph represents acceleration. * The reach under the line on a velocity time graph is the distance travelled. Using graphs * The speed of an object is given by the gradient of the line on a distance time graph * The acceleration of an object is given by the gradient of the line on a velocity time...If you want to permit a full essay, order it on our website: BestEssayCheap.com
