Question

Which of the following quantities are zero for an object traveling in a circle at a constant speed? There may be more than one correct answer. Group of answer choices Velocity Acceleration Net force Radial component of velocity Tangential component of velocity Radial component of acceleration Tangential component of acceleration Radial component of net force Tangential component of net force

Answer 1

Answer:

Zero: Tangential component of speed, Tangential component of acceleration,

Explanation:

Let's analyze uniform circular motion, using kinematics and Newton's second law , Tangency component of net force

The speed module is constant, the speed changes since its direction changes and is a vector; If there is a change in speed, there is an acceleration.

With these concepts let's analyze what quantities are zero

Quantities are:

• Acceleration.  non-Zero. It is different from zero

• Net force It is different from zero

• Radial speed component. It is different from zero, change the direction

• Tangential component of speed. Zero

•  radial acceleration component   Non-zero

• Tangential component of acceleration. Zero

• Radial component of net force  Non- Zero

• Tangency component of the net force. Zero
