Circular Motion and Gravitation Worksheet Answers: Unit 3 Circular Motion And Gravitation Worksheet Answers
This worksheet covers the concepts of circular motion and gravitation, providing exercises to help students understand and apply these principles.
Circular Motion
Circular motion occurs when an object moves in a circular path around a fixed point, called the center of rotation. Key characteristics include:
- Angular displacement: The angle swept out by the object
- Angular velocity: The rate of change of angular displacement
- Angular acceleration: The rate of change of angular velocity
Examples of circular motion include the motion of planets around the sun, the motion of a car on a curved road, and the motion of a spinning top.
Centripetal Force
Centripetal force is the force that keeps an object moving in a circular path. It is directed towards the center of rotation and is provided by an external force, such as gravity or friction.
The centripetal force is given by the equation:
Fc= mv 2/r
where:
- F cis the centripetal force
- m is the mass of the object
- v is the speed of the object
- r is the radius of the circular path
Gravitation, Unit 3 circular motion and gravitation worksheet answers
Gravitation is the force of attraction between any two objects with mass. It is described by Newton’s law of universal gravitation:
Fg= Gm 1m 2/r 2
where:
- F gis the gravitational force
- G is the gravitational constant (6.674 × 10 -11N m 2/kg 2)
- m 1and m 2are the masses of the two objects
- r is the distance between the centers of the two objects
Gravitation is responsible for holding the planets in orbit around the sun, the moon in orbit around the Earth, and for the formation of galaxies and stars.
Applications
Circular motion and gravitation have numerous practical applications:
- Engineering: Designing bridges, buildings, and machinery
- Physics: Studying the motion of planets, satellites, and other celestial bodies
- Astronomy: Understanding the formation and evolution of galaxies and stars
