Friction - The force that always opposes motion Coefficient of friction - Force of friction divided by normal force Net force - Resultant force, the sum of all forces acting on an object Free body diagrams - Physical model of a representation of forces acting on a system 2-dimensional motion - Any motion of an object is more than one line, a plane Vector independence - Changes in one vector do not cause changes in another Projectile - Any object launched into the air with no force other th...

B - A cart rolls down inclined track and is accelerating. It fires a ball straight out of the cannon as it moves. What happens to the ball? A.) It falls in front of the cart B.) It falls right back into the cart C.) It falls behind the cart C - You drop a package from a plane flying at constant speed in a straight line. Without air resistance, what will the package do? A.) Remain vertically behind the plane B.) Remain vertically in front on the plane C.) Remain vertically under plane...

Electrostatics delves into the fascinating world of static electricity, exploring the forces that arise from electric charges at rest. It unlocks the secrets behind phenomena like lightning, sparks, and even the cling of your clothes in the dryer! This branch of physics investigates the interactions between charged particles, paving the way for understanding fundamental forces in our universe.

PHY 102 Exam 4 2024/2025 VERIFIED AND UPDATED VERSION charge flows into a - √√closed circuit P = - √√IV V = - √√IR On some early automobiles both headlights went out when one bulb burned out. The headlights must have been connected in - √√a series circuit current is measured in - √√ampere (amps) The power dissipated in each of two light bulbs is the same. The potential across light bulb A is twice that of light bulb B. If the resistance of light bulb B is R, what is the...
