Acceleration that involves a change in speed without a change in direction.

Acceleration that involves a change in speed without a change in direction.

• A. Radial Acceleration
• B. Linear Acceleration
• C. G Force
• D. Angular Acceleration

Answer: (B)

Acceleration is the rate at which velocity changes. When you move along a straight path and your speed changes, the acceleration is linear because the direction stays the same while the magnitude of velocity changes. Radial (centripetal) acceleration, by contrast, comes from turning along a curved path and involves a change in direction toward the path’s center. Angular acceleration is about how quickly the rotation rate itself changes, not straight-line speed. G force simply expresses how large the acceleration is, in units of g, rather than defining a type of acceleration. So the situation described—speed changing with no change in direction—fits linear acceleration.
