GRADE 12: MECHANICS Compiled by T. Doyle Acknowledgements: C. Fairman; S. Murray and IEB SAGs , 2 Background… Mechanics is the branch of physics dealing with the behaviour of bodies (objects) when forces are exerted on them. Kinematics is the branch of mechanics dealing with changes in motion without reference to the forces causing the changes. Dynamics is the branch of mechanics dealing with the relationships between the changes in motion of bodies and the for...

Kinematics Equations Force of Gravity Between Two Objects Units of G = N∗m²/kg² Brainpower Read More 0:13 / 0:15 Kinetic Friction Static Friction Uniform Circular Motion - Velocity Velocity vector is constantly changing and is tangential to the circle of motion Centripetal Acceleration The acceleration vector always points toward the center of the circle and constantly changes direction as the object moves.

Physics 121 Final Exam Review BYU IS: Exam Review Questions & Answers/ how many standard balloons can fit into a minivan? about 200 A standard helium balloon is of the order of a foot across. The inside of a minivan is about 5 feet across by 4 feet high by 8 feet long. That is a volume of about 200 cubic feet. Probably only about 2/3 of that can be used for balloons, so 200 is probably too high, but it is closer than any of the other answers. carrying bucket at constant speed, what wor...

What is Newton's first law? An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. What are scalar and vector quantities? Examples. Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction. Scalar: time, area, volume, temperature, and mass. Vector: displacement, velocity, force, and acceleration. Difference between distance and disp...
