Homeschool Physics learning resources to help students learn more easily

Find the resources you need to learn about these subjects:

Vectors and Scalars

Motion

• Free-Falling Objects: An object at rest, dropped from a distance above the Earth, will accelerate downward at a constant rate due to gravity. Learn with this Formula Solver how to calculate this downward acceleration using your own distance, time, and final velocity values.
• Friction: When two objects rub against each other, friction acts against the force trying to move one of those objects. With this Formula Solver, learn how to calculate the friction force using the coefficient of friction.

Work and Kinetic Energy

• Energy Conversion: Energy is defined as the capacity of an object for doing work. Use this Formula Solver to learn how to convert between energy's primary units of measurement -- Joules, British Thermal Units (or BTUs), and Calories.
• Power Conversion: Power is defined as the ratio of the amount of work expended over a period of time. Use this Formula Solver to learn how to convert between power's primary units of measurement -- Horsepower, British Thermal Units per hour (BTU/hour), and Watts.

Rotation

• Centripetal Acceleration: An object in motion with velocity (v) must be accelerated inwards in order to travel in a circle or radius (r). This inward acceleration is called centripetal acceleration; see how to calculate it with this Formula Solver.
• Centripetal Force: A mass moving in a circle at constant velocity needs a force directed towards the center of the circle in order to maintain the circular motion and constant velocity. Learn how to calculate this Centripetal Force with this Formula Solver.

Gravity

• Universal Gravitation: Newton's Law of Universal Gravitation says the force between any two bodies is directly proportional to the product of their masses, and inversely proportional to the square of the distance between them. Use this Formula Solver to learn more.
• Weight: Weight is the product of the mass of an object and the gravity acting on it. Use this Formula Solver to learn how to calculate weight (in Newtons), mass (in kilograms), or gravitational constant using the other two values (which you can enter yourself).
