Circular Motion

What is the definition of Tension?

• A pulling force transmitted axially through a string, cable, or chain, which can act as a centripetal force.

• A force that compresses an object, causing it to shorten.

• A force that acts perpendicular to the surface of an object, causing it to slide.

• A force that resists the motion of an object, acting in the opposite direction.

What is Uniform Circular Motion?

• The movement of an object at a constant speed around a circle with a fixed radius.

• The movement of an object in a straight line at varying speeds.

• The movement of an object that accelerates in a circular path.

• The movement of an object that changes direction but not speed.

What is a Fictitious Force?

• A force that acts on a mass in an inertial frame of reference.

• A nonexistent force that appears to act on a mass whose frame of reference is accelerating relative to an inertial frame.

• A force that is always present in a gravitational field.

• A force that can be measured directly using a scale.

What does the term Tangential mean?

• In the direction of a tangent line to a curve, describing the direction of velocity in circular motion.

• Relating to the center of a circle or sphere.

• Describing a force that acts perpendicular to the direction of motion.

• Indicating a point of intersection between two lines.

What is the definition of Revolution?

• One complete trip or cycle of an object moving in a circular path around a central point or axis.

• A sudden and radical change in political power or organizational structures.

• The act of rotating around an axis or center.

• A significant increase in the speed of an object.

Centripetal Force

• The force that pulls an object outward in a circular path.

• The net force directed toward the center of a circle that causes an object to follow a circular path.

• The force that opposes motion in a circular path.

• The gravitational force acting on an object in motion.

Centripetal Acceleration

• The acceleration of an object moving in a straight line.

• The center-seeking acceleration of an object in uniform circular motion.

• The acceleration due to gravity on the surface of the Earth.

• The acceleration experienced by an object in free fall.

What is the definition of Velocity?

• A scalar quantity representing the speed of an object.

• A vector quantity representing the rate of change of an object's position, which is always tangent to the circular path.

• The total distance traveled by an object in a given time period.

• A measure of how fast an object is moving in a straight line.

Centrifugal Force

• A real force that pulls objects towards the center of a circular path.

• A fictitious, outward-directed force that is incorrectly perceived to act on an object moving in a circular path.

• A force that acts in the same direction as the motion of an object.

• A force that opposes the motion of an object in a straight line.

What is the definition of 'Period' in the context of motion?

• The time required for an object moving in a circular path to make one complete revolution or cycle.

• The distance traveled by an object in a straight line.

• The speed of an object at a given moment.

• The force acting on an object in motion.
