Physics of nerve cells: Electrochemistry and circuit components of axons Physics of nerve cells: Neuronal membranes as nature's capacitors Physics of nerve cells: The speed of a neural impulse Sound: How movements influence an ultrasound Sound: Resonance in a tube Sound: Clinical applications of tuning forks
Apply: impulse (practice) | Impulse | Khan Academy The crumpling increases the time over which the car's—and more importantly, the passengers'—impulse occurs Consider the following example Two cars undergo crash testing with a crash test dummy inside The two dummies, A and B , are wearing sensors which record force over time during the collision The data from each sensor is graphed below
Science Courses Updates in July 2021 - Khan Academy Help Center We are excited to share that we've made significant enhancements to our Science domain Some of our formerly science “beta” courses are now ready to go and we have added new content to the following courses: High school biology (formerly 'beta') High school physics (formerly 'beta') AP Environmental sciences (formerly 'beta') AP Physics 1 (formerly 'beta') That said, it is worth noting
