Compare the three levels

Support

Easier questions on the same topics, for students who need more practice with the basics.

Questions: 20 (20 medium)
Grade range: Grades 7 to 12
Topics: Motion & energy

Sample questions

A device transfers 156 J in 6 s. Find average power in W.
An object moves at constant velocity 26 m/s for 39 s. Find displacement in m.
A device receives 5400 J and delivers 4050 J of useful energy. Find its efficiency as a percentage.

Core

Questions at the expected level for the grade.

Questions: 20 (20 medium)
Grade range: Grades 7 to 12
Topics: Motion & energy

Sample questions

A device transfers 756 J in 12 s. Find average power in W.
A perpendicular force of 132 N acts over 1 m². Find the pressure in Pa.
A device receives 3500 J and delivers 700 J of useful energy. Find its efficiency as a percentage.

Challenge

Harder questions on the same topics, for students who are ready to stretch.

Questions: 20 (20 challenge)
Grade range: Grades 9 to 12
Topics: Motion & energy

Sample questions
