Is it possible to defy gravity? Not really. With force and inertia, we can act against it for a little while, but, eventually, gravitational force will pull us back to Earth. The relationships among mass, force, and inertia are all...

Scientists state that the higher something is above the earth, the greater the gravitational potential energy. Does this mean there is more gravity acting on the moon than on an apple falling from a tree? Scholars adjust the distance...

What would a baseball game look like on the moon? Probably a lot of home runs! A creative activity explores the motion of a projectile on the surface of different bodies in the solar system. Participants adjust the angle and...

Let the star's color be the guide! The color of a star indicates its temperature and its mass and distance affect the gravitational force. The lesson presentations address these concepts as well as how the theory of special relativity...

Define six common forces: propulsion, air resistance, water resistance, friction, gravity, and upthrust. A picture of a Smart Car is displayed with arrows showing all of the forces acting on it when it is motion. A picture of a rubber...

Definitions of gravity and weight and the calculations involved with their manipulation are covered here. The equations and resource links will be valuable to show a physics class. Use it as a note-taking support for your lecture on...

This PowerPoint is a gem! Seventy-eight slides present an entire introduction to matter in bullet-point fashion. Viewers learn about everything from mass and inertia to phase changes and gas laws! The only glitch is that the links to...

Have you ever wanted to turn off gravity? This simulation allows learners to do just that in addition to altering other variables. Scholars can move the sun, Earth, moon, and space station to see how distance affects gravitational pull....

Why was Sir Newton so important to the field of science? Pupils discuss his contributions, specifically his Third Law, as they learn about gravity and the center of mass. They work multiple problems to ensure their understanding and...

Budding scientists fall hard for a gravitational field strength activity! Physics pupils compare the masses and distances relative to the center of planets using an interactive from a Circular and Satellite Motion series. Individuals...

Let's talk torque! Science scholars evaluate experimental setups during an interactive from the Rotation and Balance series. Individuals calculate the torque of differently arranged weights to determine the effect they have on a balanced...

The focus of this resource is to teach young students about some of the basic components of force and motion. Students view slides which give examples of gravity, force, motion, magnets, and wind. Then, they must choose one of those...

Does size or mass impact gravitational pull? Scholars experiment with force pairs to answer that question. They can change the size, mass, and distance between the objects using an engaging simulatoin. This allows pupils to visualize the...

Many realistic situations of active forces are presented here along with diagrams. The direction of movement, acceleration and gravity are labeled on each picture to help understanding.  A summary of the direction of acceleration...

Examples and practice questions will help real-life understanding of the Principle of Moments concept. These great slides define the types of levers and pivots, and then give examples of the typical seesaw situations that help the...

May the mass times acceleration be with you. The presentation covers forces, Newton's three Laws of Motion, momentum, and vectors.

Is your class struggling with Newton's Second Law? Then show them a presentation that covers everything physics scholars need to know about forces. Starting with gravity, the slides focus on Newton's Laws of Motion, and end with an...

Go around and around in your physics class with this presentation on circular motion. Diagrams bring the definition to life. Formulas for angular acceleration, centripetal force, gravitation, and potential in a radial field are given....

Are you feeling weighed down by your current gravitation presentation? Assign a hands-on interactive instead! Physics scholars work through a series of progressively harder questions about mass, distance, and gravity using an online...

Cliff diving is more than an adrenaline rush ... it's a lesson in physics! Scholars adjust the height of a cliff and plot the resulting velocity and position over time on graphs. They also can incorporate air resistance to monitor the...

Why do many tightrope walkers use a balancing pole? The simulation explores the benefits of balancing poles and the features that are most important. Pupils control the pole length, pole mass, pole stiffness, and the initial angle of...

Do your young physicists get a little unbalanced when it comes to talking about torque? Scholars examine the effects of weight and distance on a balanced system with a simple interactive from the Rotation and Balance series. The resource...

There is scant information on these slides: definitions of gravity and force, and the fact that objects fall at the same speed. Two slides give learners an activity to try to demonstrate aspects of gravity. Although the activities are...

Explore gravity, force, and mass as some of the natural forces in the universe. Each slide provides information and examples that describe each concept. Learners are encouraged to throw a basket ball and a bean bag into the air to...
