A biography of the scientist that developed the theory of gravity and founded the three basic laws of motion, Isaac Newton.

Assess your understanding of force, mass and acceleration and the relationship amongst the three with this interactive multiple choice quiz. Immediate feedback is offered.

The large scale horizontal flow of air in the atmosphere is driven by the imbalance of net radiation over the globe. This resource introduces us to the physical laws governing the horizontal motion of air. It also describes types of...

Through ten lessons and numerous activities, students explore the natural universal rules engineers and physicists use to understand how things move and stay still. Together, these rules are called "mechanics." The study of mechanics is...

Use this simulation to see the results of applying a force to move an object. Analyze forces and friction using graphs.

In this activity, students' use a force sensor and a motion detector to collect force and acceleration data for an object moving up and down hanging from a spring. They use the data to test Newton's second law, and to estimate the mass...

This activity provides students an opportunity to investigate Newton's first law by observing inertia in a variety of experiments. Students will hypothesize on possible outcomes, write observations of what has happened, and apply...

Learners conduct an experiment that will reinforce their understanding of Newton's Second Law. Using simple objects, students control force, mass, and acceleration, and how each is related to each other.

Learners will create a gravity ball launcher to demonstrate their understanding of mass, force, momentum, and motion. The students will use critical thinking, measurement, and observation and analysis of data to make changes and improve...

For this lesson, students develop their own scientific experiment to test Newton's hypothesis that the acceleration of an object depends on the net force acting upon it and its mass. After completing their designed experiment, students...

This lesson focuses on Newton's Second Law including the formula Force = mass to the x power acceleration, an example of how to calculate the force needed to accelerate based on mass, and a link to a test.

Help your students explore how the motion of objects changes during a collision. This website includes work samples, phenomena, assessment templates, and videos that focus on collision design solution.

[Free Registration/Login Required] Read a force scenario, and then analyze the graphs provided to gain an understanding of inertia and force. After the activity, answer three challenge questions to check for understanding.

[Free Registration/Login Required] Use the interactive diagram to solve a projectile motion problem. After the activity, answer a challenge question to check for understanding.

Students discuss forces acting on objects in a trajectory motion. They review notes, study equations, solve projectile motion problems, and determine experimentally the impact point of a ball in projectile motion.

The interactive simulation demonstrates the conservation of momentum through a Newton?s Cradle simulation.

[Free Registration/Login Required] Explore how angles affect the projectile motion of a thrown object. After the activity, answer a challenge question to check for understanding.

In this guided inquiry demonstration, a person on rollerblades and a medicine ball are used to teach the concept of conservation of momentum. Various sorts of collisions are used to show how momentum is conserved within a system.

Students improve their understanding of momentum conservation and learn that a recoiling object in an elastic collision will transfer more impulse than if it collided inelastically.

Through illustrated examples and interactive practice, students explore Newton's ability to relate the cause for heavenly motion (the orbit of the moon about the earth) to the cause for Earthly motion (the falling of an apple to the...

Explore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.

This physics tutorial aims to model and predict not the motion of just one object, but rather what happens when two or more objects collide. The concept of momentum will be the main focus of this module.

Instructions for a science demonstration of Newton's first law of motion using common supplies. Learn how to turn the demonstration into an experiment.

Investigate Newton's first law of motion using just a set of wood blocks.
