Acceleration vs. Constant Velocity
Observe the animation of the three cars below. Use the animation to answer the three questions. (If necessary, review the definition of acceleration.)
Practical Physics
This website is for teachers of physics in schools and colleges. It is a collection of experiments that demonstrate a wide range of physical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians.
Newtons Laws
Force When forces are unbalanced, objects accelerate. But what factors affect the amount of acceleration?

Accelerometer
Created by our friends at Nerd Island Studios, the Accelerometer Interactive allows learners to collect data of velocity as a function of time for their mobile device. If the device has a built-in accelerometer, the Accelerometer Interactive will be able to plot an acceleration vs. time graph as the device moves. That's both nifty and risky.

Graph That Motion
The Graph That Motion Interactive consists of a collection of 12 challenges. Each challenge presents learners with an animated motion of a car. After viewing the motion, one must match the motion to the corresponding position-time or velocity-time graph. Feedback is immediate and mulitple attempts to get the matching graph correct are allowed. Launch Interactive
Here's what fruits and vegetables looked like before we domesticated them
Next time you bite into a slice of watermelon or a cob of corn, consider this: these familiar fruits and veggies didn't always look and taste this way. Genetically modified foods, or GMOs, inspire strong reactions nowadays, but humans have been tweaking the genetics of our favourite produce for millennia. While GMOs may involve splicing genes from other organisms (such as bacteria) to give plants desired traits – like resistance to pests, selective breeding is a slower process whereby farmers select and grow crops with those traits over time.
