This is a student check list or guiding questions used to identify the different types of forces acting on an object. Students can ask themselves a question to determine the presence or absence of each type of force, the chart includes clues that student will use to figure out how to draw the given forces, and it also includes an example. LEP Students have found the chart useful since the activity is organized in steps, and it includes visual illustrations.

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

Use frictionless ramps, and and a dynamic cart to test the relationship between the change in the kinetic energy of a system and the work done to stop it. Let the students discover the physics describing the flow of energy on a mechanical system. Use the power of technology to measure the position, velocity, and acceleration of the system and make calculations with precision and accuracy.

There is always a misconception between mass and weight. Are they the same thing or different concepts? In this lab students have the opportunity to explore the relationship between mass (amount of matter) and weight (pull of gravity) and understand the connection between both concepts using simple low tech lab equipment. Students are able to understand why we can use a spring scale to measure the mass of an object.

Students can track the motion of a pull-back car and study its acceleration, Students will plot a velocity - time graph and calculate the acceleration of the car from the slope of the line. Students can measure the uncertainty of the measurements, and calculate the percent error of their experimental result. This lab can be used in high school, or college level.

Give the students the unique possibility to experience hands-on activities to explore heat. Students will perform different experiments illustrating the three heat transfer mechanisms: Conduction, convection, and radiation.

Students will measure the amplitude, period and frequency of traveling waves from a diagram. Students practice calculating the period, frequency, and speed of waves. Students make a venn diagram comparing longitudinal waves to transverse waves.

In this activity student will use a motion sensor to collect the position of a pull-back toy cart. Students will use the equations of kinematic to determine the acceleration from a velocity vs time graph, or a position vs time graph. Students will use the information obtained to answer the post lab questions. Students also will learn and practice on data collection, and display using data tables and graph.

Use an ammeter and a voltmeter to measure the current and the voltage in several resistors connected in series, and in parallel. Explore how the currents and the voltage are related in each configuration, and use ohm's law and the law of conservation of charge to derive the equations for equivalent resistance in both series and parallel configurations. CPO physics equipment was originally used, but you may use any standard resistors.

Use the law of conservation of momentum to predict the velocity of a ball before it collides with a stationary lab cart. The ball and the cart will stick together and continue to move together after colliding. this lab uses an added part made on a 3D printer. I used a 4.8 cm diameter metal ball from the energy ball kit used for physics. Caution is required when handling heavy objects, do not use open toe shoes and use eye protection.

Use the Arduino uno, and a photoresistor module to make a photogate you can use to measure the speed of a moving object.

Create velocity vs. time graphs using the information from the given position vs. time graphs. The velocity is calculated from the slope of the line in the position vs. time graph.

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

Use the HCSR-04 ultrasonic sensor to measure force. Led your students build their own force sensor and learn the principles of sound propagation, and reflection, hook's law, and instruments calibration. Use the sensor made to measure the force in other lab activities. Cultivate creativity, and ingenuity by letting the students make their own designs, using different materials and their own designs. Learn how to use the arduino board to collect data in the physics lab.

Determine the acceleration of a wind-up cart using the arduino uno board and the ultrasonic sensor. The acceleration is calculated from the quadratic fit on the position vs time graph, or from the slope on the velocity vs time graph.

Students will be able to measure the acceleration of a cart down the ramp for different inclination angles, collected data may be used to predict the acceleration of the cart for an angle of 90 degrees by extrapolation. A graph of acceleration vs. sine(angle) should yield a strait line with a slope equals to the free fall acceleration g. A key and student sample data is provided.

Use video analysis to measure the acceleration of a falcon 9 rocket. How to determine the position, velocity, and acceleration of the rocket over time? How to use the data collected to analyze the rocket's motion? This lab activity is divided in four main sections, Introduction, data collection and data plotting , Analysis questions, and post-lab questions. any online source showing telemetry from a rocket launch may be used.

Use logger pro or any other data logger, a pipe, and a microphone to measure the speed of sound on air. Students will calculate the speed of the sound wave by measuring the round trip distance sound makes inside a pipe 1m long os more and measuring the round trip time using a microphone connected to a data logger like vernier logger pro, lab quest, pasco capstone, or an arduino board connected to a microphone. The speed of the sound is calculated as the round trip distance over the round trip ti

Students will learn how to determine the spring constant of a spring using the law of conservation of energy, students will also be able to study the mathematical relationship between the stretching length of a spring and the velocity of a marble launched by it. the collected data and graph can be use to predict the maximum height the ball would reach under a preset stretching length of the spring.

Students will determine the spring constant of a spring experimentally. Students will use a sample data to make calculations of mass, force and energy of a spring mass system. the data can also be measured from the system using a motion sensor located below the mass, and setting the system to oscillate for several seconds.
