What occurs when an object travels in a curved path
1 answer:
<span>When an object travels in a curved path, there must be a force acting toward the center of the circular trajectory. This force is called "centripetal force", and it cause an acceleration of the object, called "centripetal acceleration". The effect of this acceleration is that the velocity of the object changes in direction: however if the circular motion is uniform, the speed (=the magnitude of the velocity) does not change. In this case, the magnitude of the centripetal force is given by

where m is the mass of the object, v its velocity, and r the radius of the circular path.</span>

Answer:
c. joules
Explanation:
The rate at which a force displaces a mass a horizontal distance is measured in joules. In science, this phenomenon is known as work done.
Work done can be defined as the rate at which a force acting on an object or a body causes it to experience a displacement. The work done is a scalar quantity and is measured in joules (J).
Mathematically, work done is given by the formula;
Work done = force * distance
Where,
- W is the work done
- F represents the force acting on a body.
- d represents the distance covered by the body.
