Answer 1

1. An object moving in uniform circular motion has constant speed.2. The velocity and acceleration are always perpendicular to each other.3. The acceleration vector changes only the direction of the velocity.4. Circular motion does not have constant velocity because the direction is always changing.5. A system for describing the locations of objects is called a coordinate system.6. Using the Big G equation, if the mass of object one doubles and everything else stays the same, the force of attraction will double.7. Using the Big G equation, if the distance doubles and everything else stays the same, the force of attraction will decrease to one-fourth.8. Using the formula

, if the velocity doubles but the radius stays the same, the acceleration will quadruple.9. Using the formula

, if the radius doubles but the velocity stays the same, the acceleration will decrease to one-half.10. The acceleration of an object moving in a circle that is directed toward the center of the circle is called centripetal acceleration.11. Any force that causes an object to move in a circle is called a centripetal force.12. Anytime an object moves in a way that traces out a circular path, it is called circular motion.13. A straight line or plane that touches a curve or curved surface at a point is called a tangent.14. Cycles per second is called frequency.15. Time for 1 complete cycle is called the period.16. There is a force of attraction between any two objects with mass, which is called gravity.17. The Universal Gravitational Constant is a constant of proportionality in the law of universal gravitation.18. The Law of Universal Gravitation says that all objects in the universe are attracted to each other.19. If Earth's gravity were suddenly doubled, the moon would be pulled towards the Earth with a greater force, causing it to move in a lower orbit.20. If the Sun's gravity ceased to exist, the Earth would no longer be pulled towards the Sun and would move in a straight line away from the Sun.21. If the Moon's orbital velocity suddenly slowed down, its orbit would become larger and more elliptical.22. If the Earth's orbital velocity suddenly increased, its orbit would become smaller and more circular.23. The Yeti cup doesn't slowly creep toward you due to Universal Gravitation because the gravitational force between you and the cup is very small.24. The most accurate way to determine how long it will take an object to fall from 1 m in a world without friction is to use the formula

, where

is the height and

is the acceleration due to gravity.
