Kinematics
Motion in one dimension
RealVideo®Measurements of falling times for different heights and comparison to dimensional analysis.
RealVideo®Demonstrating and calculating the average velocity of a bullet, with considerations of uncertainty in measurement.
RealVideo®Demonstrating free-fall motion of an object, using strobe-lighting on a falling ball to show increasing velocity.
RealVideo®Cross product calculation using sin(θ); finding direction by corkscrew method; and importance of right-handed coordinates. Demonstration of this method using a corkscrew in a potato.
Motion in Two Dimensions Including Projectile Motion
RealVideo®A golf ball is fired directly upward from a moving cart and is then caught by the cart as the ball comes down, demonstrating that vertical and horizontal velocities of a projectile are independent.
RealVideo®Demonstration of maximum horizontal displacement for projectile motion within calculated uncertainty for 45°.
RealVideo®Demonstration of the same displacement for 30° and 60° with different times.
RealVideo®Demonstration that a ball fired at a monkey at the moment it begins free fall will still hit the monkey.
