Question 1
A net force F = ct, where c is a positive constant, acts along the x-axis on an object of mass m that starts at rest at x = 0 when t = 0. What is the object's position at time t?
Is AP Physics C hard?
About 73% scored 3 or higher on each exam in May 2025. The hard part is setting up the physics before the calculus.
| Mechanics, 3 or higher | 73.2% of 65,980 |
|---|---|
| E&M, 3 or higher | 72.9% of 29,708 |
| Scored 5 | 21.7% Mechanics, 25.2% E&M |
| Mean score | 3.30 Mechanics, 3.38 E&M |
What makes it hard
- You set up integrals and differential equations from a principle.
- Many questions are symbolic: the answer is an expression.
- E&M is new to most students; Mechanics builds on earlier physics.
