Question

Match each motion scenario with the correct type of forces acting on the object. (Lesson 2)

(4 points)

A car speeding up from a stoplight

A satellite moving at a constant speed in a
straight line

A soccer ball rolling to a stop on grass

A book sitting still on a desk

# Unbalanced forces

# Balanced forces

# Balanced forces

# Unbalanced forces

Answer 1

- A car speeding up from a stoplight — Unbalanced forces (net forward force → acceleration)
- A satellite moving at a constant speed in a straight line — Balanced forces (net force zero → no acceleration)
- A soccer ball rolling to a stop on grass — Unbalanced forces (friction/drag produce a net force opposite motion → deceleration)
- A book sitting still on a desk — Balanced forces (weight and normal force cancel → no net force)
