What is displacement?
Displacement (Δx) is the change in position. It's a vector!
Define velocity.
Velocity (v) is the rate of change of displacement. Also a vector!
What is acceleration?
Acceleration (a) is the rate of change of velocity. It's a vector.
Define work in physics.
Work (W) is the transfer of energy by a force. .
What is kinetic energy?
Kinetic Energy (KE) is the energy of motion. .
Define impulse.
Impulse (J) is the change in momentum. .
What is torque?
Torque () is the rotational analog of force. .
Define centripetal acceleration.
Centripetal acceleration () is the acceleration directed towards the center of the circle.
What is gravitational force?
Gravitational Force () is the attractive force between two masses. , where G is the gravitational constant.
Define momentum.
Momentum (p) is the product of mass and velocity. . It is a vector quantity.
How do you analyze projectile motion?
Analyze horizontal and vertical motion separately. Horizontal motion: constant velocity (). Vertical motion: constant acceleration due to gravity ().
How do you solve problems involving inclined planes?
Resolve forces into components parallel and perpendicular to the plane. ,
How do you analyze orbital motion?
Set gravitational force equal to centripetal force: .
How do you apply Newton's Second Law for Rotation?
Use the equation to relate net torque to rotational inertia and angular acceleration.
