1. The velocity-time graph encloses an area of a triangle with base 4.0 s and height 10 m/s plus a rectangle of 3.0 s by 10 m/s. What displacement is shown?
The area is 0.5 x 4.0 x 10 = 20 m plus 3.0 x 10 = 30 m, giving 50 m.
This public preview is being prepared so visitors can try the subject before subscribing.
This public preview page identifies the planned Year 11 ACT Physics demo route and links it to curriculum coverage while the reviewed sample question set is being completed.
The planned public sample is for Year 11 ACT Physics practice and will open after the demo questions are reviewed.
Practice motion, forces, energy, waves, electricity, fields, light, matter, data analysis, and scientific modelling.
The route is public now; the exercise and test preview will become available after the curated question set is ready.
Compare this demo with the ACT Year 11-12 Physics curriculum page to scan related topics, subtopics, and pathway coverage.
These sample questions are visible on the page before login. They show ACT BSSS Year 11 Physics motion, energy, electric fields, waves, magnetic flux, and light-and-matter data with diagrams and graphs before opening the demo.
The area is 0.5 x 4.0 x 10 = 20 m plus 3.0 x 10 = 30 m, giving 50 m.
Ohm's law gives I = 24 / 6 = 4.0 A.
Light bends away from the normal when it enters a faster optical medium.
Centripetal acceleration is v2 / r = 3.02 / 2.0 = 4.5 m/s2.
120 to 15 is three halvings: 120, 60, 30, 15. Three half-lives take 15 days, so one half-life is 5 days.
The area under the linear graph is 0.5 x 0.09 x 18 = 0.81 J.
ACT BSSS Year 11 Physics practice should help students connect equations to visible evidence: motion, energy, electric fields, waves, magnetic flux, and light-and-matter data. These examples preview that visual reasoning before the no-login Physics demo.
Not yet. The Year 11 ACT Physics demo route is public, but the interactive sample questions will open after the reviewed public set is ready.
No sign-up is required to view the preview status. The no-login interactive demo will be available after the sample set is completed.
This demo is linked with the ACT Year 11-12 Physics curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
