Parallel circuits often provide less of a challenge for teens than parallel parking. An installment of a series on parallel electric circuits requires learners to solve increasingly difficult  levels of calculations. Each level...

Horizontal and vertical speeds change as projectiles move through space. As part of a series on vectors and projectiles, scholars create vector diagrams to compare these speeds at various locations. They they determine the values for...

Matchy-matchy no longer exclusively applies to fashion. Scholars work through three levels of practice matching position and velocity graphs. Part of a series covering dimensional kinematics, each question provides immediate feedback and...

Three sections review the key skills covered in a series on dimensional kinematics. The first covers the difference between distance and displacement. The second addresses the relationship between velocity and slope. The third includes...

Scholars demonstrate understanding of kinematic graphs through matching dot graphs to position time graphs, dot graphs to velocity graphs, and a mixture of the two. If users feel stuck or confused, a Help Me! button offers an explanation...

Scholars work through three activities building motion diagrams as part of a series exploring dimensional kinematics. Each activity has six descriptions requiring application of velocity vectors, acceleration vectors, and challenge...

Pupils apply their understanding of motion to 11 practice problems as part of a series on dimensional kinematics. They view a dot diagram animation and read descriptions to identify which match. As a bonus, the interactive offers...

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...

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...

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...

Math is a lot like building blocks—it requires a solid foundation. A short performance task has pupils consider the volume of a cubic block. It then asks mathematicians to find the surface area and volume of a prism made from stacking...

Most pupils learn quickly how to apply Newton's Second Law equation to calculate net force. However, many struggle to determine net force before calculating the value of an unknown force from a force diagram. As part of a larger series...

Physics formulas provide more interest than simple math equations thanks to an informative installment from the series on Newton's laws of motion. The formulas guide pupils' thinking about how varying a quantity affects the rest of the...

A common complaint among physics scholars studying Newton's laws of motion concerns drawing free-body diagrams. To practice the required pre-requisite skills for free-body diagrams, individuals identify which forces act in specific...

Free-body diagrams display all forces acting on an object, helping scientists represent Newton's Laws of Motion. Scholars read a short description of motion and view the free-body diagram to begin the installment of a larger series on...

Scholars focus on associating balanced forces with at rest or constant velocity motion and unbalanced forces with acceleration or deceleration. Practice problems with immediate feedback allow for quick success in an installment of the...

Scientists use many different kinematic representations of motion. Review each of them with the help of an engaging interactive that is part of a larger series on Newton's laws of motion. The resource provides three levels of challenge...

How do police determine the speed of a car that has hit a stopped vehicle? Scholars determine the momentum of the car system both before and after a collision. They identify instances where the law of conservation of momentum appears to...

Pupils read a description of a physical situation and select the free-body diagram that best matches. As part of a series on applying Newton's Laws of Motion, scholars reinforce their skills applying forces and considering their relative...

Why are gym walls padded and cars required to have air bags? Scholars observe two similar situations, such as those listed above, with only one variable altered. They identify the different variable and determine how the variation...

Scholars quantitatively apply their knowledge relating impulse, force, and time in the collision of objects. Three progressive levels challenge pupils with different ways of analyzing these problems. They identify multiple collision...

How do law enforcement officers determine the strength of an explosion based on the movement of objects around the point of origin? Scholars inspect the relative mass and velocities of two cars before and after an explosion. They perform...

Many scholars confuse velocity and acceleration even after they correctly solve basic problems. Using an interactive, part of a series on vectors and projectiles, with immediate feedback focuses their attention on the up or down...
