Question

Identify two types of motion where an object's speed remains the same while it continues to change direction

Answer 1

• motion in which acceleration is orthogonal to travel direction
• motion in which speed is constant

Step-by-step explanation:

1) Any motion in which the acceleration is orthogonal to the direction of travel will have this characteristic:

circular motion in a plane

motion of a charged particle in a magnetic field perpendicular to the direction of travel

__

2) Motion in which the speed is constant, regardless:

motion of a photon through a varying gravitational field
