Curated OER
@23 Accelerated Frames of Reference: Inertial Forces #23a Frames of Reference: The Centrifugal Force
Students distinguish between the centripetal and centrifugal forces.
Curated OER
Newton and his Laws
High schoolers explore Newton's laws, including what they state, and what the intuitive meaning is of the first and third laws.
Curated OER
Newton's Laws
Students examine and discuss Newton's Laws and discover his contribution to physics. In groups, they participate in an experiment in which they much apply the Laws to the world around them. They describe contact and conservative forces...
Curated OER
Acceleration and You
Students discuss and view examples of acceleration. They work together to determine acceleration rates in two ways. They analyze their data and discuss.
Curated OER
Eratosthenes And Radius of the Earth
Students calculate the radius of the earth. They use the method and data suggested by Eratosthenes. They investigate the interrelationships among mass, distance, force, and time through experimental processes.
Curated OER
Impulse and Momentum
Learners are introduced to the concepts of impulse and momentum and problem solving strategies for these types of problems. In groups, they discover the law of conservation of momentum and share their answers with the class.
Curated OER
Accelerated Frames of Reference: Inertial Forces
Students examine how when applying the laws of motion to an object in an accelerating frame, using coordinates defined in such frame, one must always add an "inertial force", representing forces caused by the frame's acceleration.
Curated OER
Looking into Eratosthenes' Radius of the Earth
Students, in small groups, research Eratosthenes and his calculations of the Earth's radius. They write a summary of the person, the experiments and his calculations to determine how accurate Eratosthenes was in his estimations of the...
Curated OER
Four Forces of Flight
Students explore the four forces of flight. They investigate the four forces of flight: lift, drag, thrust and weight (gravity). They experiment with flight-testing various objects commonly found around the house and constructing paper...
Curated OER
Gyrocopter - Describing Rotary Motion
Pupils calculate angular displacement, velocity and acceleration of gyrocopters. In this physics lesson, students compare data taken from 3 different gyrocopters. They explain how differences in construction material affect rates of...
Curated OER
Worksheet 9
In this math worksheet, students examine how the moment of a force about a point is defined. They look at the 2 problems to define the information contained in them.
Curated OER
Cell Transformation in Tobacco Leaf Disks
Students review the basic principles of plant cell structure, tissue culture, sterile technique, and cell transformation. Next students complete a plant transformation experiment using whole plant material in order to view evidence of...
