Another Angle on Fnet = m*a
The Net Force Problems Revisited Video Tutorial discusses a logical strategy for approaching an analysis of a situation in which a force is applied to an object at an angle to the horizontal in order to accelerate it across a level surface.
The video lesson answers the following questions:
- How do you analyze a situation where an angled force causes an acceleration along a horizontal surface?

Concept Builders: Solve It! (with Vectors and Fnet = m•a)
Students love Concept Builders and this one is a perfect follow up to the video. There are three levels of difficulty, each having two nearly identical problems. And tap the Help Me! button to get some help specific to the problem. Test your understanding with our Solve It! Concept Builder.
Minds On Physics, Mission 2DF2, Fnet = m•a and Forces at Angles
Minds on Physics can provide a student a rigorous work-out on any topic. Give your brain some exercise and your conceptual understanind a test with a MOP mission. Each question comes with a thorough commentary of the Physics associated with that question. Give Mission 2DF2 a try as a perfect follow-up to this video.
