Model choice
A block moves at constant velocity across a rough surface. What must be true about net force?
The net force is zero because the acceleration is zero, even though friction may be present.

Sample prompts
Graph interpretation
A velocity-time graph has a positive constant slope. What does that show?
The object has constant positive acceleration.
Energy reasoning
A cart rolls down a ramp with negligible friction. What energy transfer should be explained?
Gravitational potential energy decreases while kinetic energy increases.
