U2 Physics

Use a ripple tank and a wave generator to measure the speed of a ripple in a ripple tank. Students will be able to set three or more different values of frequency on the wave generator, and them take a picture of the waves produced using a digital camera. with the picture the students can measure the wavelength of the waves, and plot a graph of frequency versus inverse of wavelength. The slope of the line represents the speed of the wave. will the speed of the wave be affected by changes in the

Practice on solving problems related to conservation of linear momentum for inelastic and elastic collisions, and practice on determining the impulse, and final velocity of a ball bouncing off a wall

Students will practice on adding the following force vectors using the components method, graphically and analytically. Students may determine the percent difference between the numerical results to compare the values. Teachers may give extra credit to students with e percent difference less than 2%, or so. Students may work on this activity in groups to make it more competitive. This activity is target to students in Pre AP Physics or AP Physics class.

Students add vectors using the head to tail method to determine the velocity of an airplane in reference to the ground. The velocity of the airplane in reference to the air, and the wind's velocity is given. Teachers may ask the students to work in groups and build their own arrows from cardboard and straws, draw the airplane and the angles in sticky notes and combine them to get the different situations presented, or new combinations. Every segment is one inch long.
