Friction and gravity are always at odds! Learners complete a set of activities to explore the relationship between friction and gravity. Groups make conclusions about the factors that affect the amount and type of friction between surfaces.

In this force and motion worksheet, students read six paragraphs with numbered sentences about force and the laws of motion and answer one question.

Force acts on objects in mysterious ways ... until now! A comprehensive presentation explains the balance of forces acting on objects. Learners draw free body diagrams to show these invisible forces and make force calculations.

In this forces worksheet, students explain how a car's motion is affected by different forces. This worksheet has 3 short answer questions.

In this friction worksheet, students will read about fluid friction and examples of fluid friction. Students will also explore the role fluid lubricants have in reducing friction between two surfaces. Then students will answer two short...

At the end of a general physics course focused on light and electricity, you can administer this exam. Concepts covered include electromagnetism, circuits, induction, light rays, lenses and mirrors, characteristics of light, electron...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

In this erosion deposition learning exercise, students fill in 36 blanks to complete sentences about the formation of soil, the forces of erosion, physical and chemical weathering, sediments and soil deposition.

This comprehensive midterm exam covers a vast array of topics typical to high school physics curriculum. Problem solving and mutliple choice questions are incorporated. Review the exam to make sure that the content is suitable to your...

The funny thing about friction is that you couldn't get anywhere without it, yet it still acts to slow you down as you're getting there. Here is an easy project to measure the effects of friction.

Covers the meanings of force, friction, and gravity, and the differences between magnetic and elastic spring force, and between weight and mass. The effect of air resistance on an object's motion is also touched upon.

Explore the effects of forces around us in the world.

[Free Registration/Login may be required to access all resource tools.] Understand the effects of magnitude of force pairs between objects. Know the differences between kinetic and static friction.

Experience the effect of friction, air resistance, and applied force upon a sledder. The speed, acceleration, and force values are displayed as the sled moves. Learners can vary the mass of the sledder and the size of the parachute...

A collection of resources on how humans use machines and tools to meet their needs. Covers simple and complex machines, subsystems that transfer forces, mechanical advantage, speed ratio, the effect of friction, efficiency, the science...

This site is an interactive app of an inclined plane showing the effect of the angle, the weight of the block, and the friction as a block is pulled up an incline.

This virtual experiment is designed to let the student measure the relation between muzzle velocity (which determines projectile energy), gravitational potential and the effects of frictional drag caused by wind speed blowing opposite to...
