1. On a frictionless surface, what is the net force on an object if only gravity and normal force act on it horizontally?

Equal to mg Zero Equal to N Equal to μmg

2. An applied force of 50 N pushes a 10 kg box. Friction is 20 N. What is the acceleration?

2 m/s² 3 m/s² 5 m/s² 7 m/s²

3. On an incline, which component of weight acts parallel to the slope?

mg cos θ mg tan θ mg sin θ mg / cos θ
