Question

1. a student feels pushed backward when a bus starts moving because of: a. friction b. newtons first law c. newtons second law d. newtons third law

Explanation:

Newton's First Law (Law of Inertia) states that an object at rest stays at rest and an object in motion stays in motion unless acted upon by an external force. When the bus starts moving (external force acts on the bus), the student's body (initially at rest) tends to stay at rest (due to inertia), so the student feels pushed backward relative to the moving bus. Friction (A) is about resistance to motion between surfaces. Newton's Second Law (C) relates force, mass, and acceleration ($F = ma$). Newton's Third Law (D) is about action - reaction pairs.

Answer:

B. Newton’s First Law
