Compare and contrast static and kinetic friction.

Both are forces that oppose motion ( $\F_f = \mu F_N$ ). Static friction prevents motion, while kinetic friction opposes motion of sliding objects.

Compare elastic and inelastic collisions.

Elastic: Both momentum and kinetic energy are conserved. Inelastic: Momentum is conserved, but kinetic energy is not.

Compare and contrast period (T) and frequency (f).

Period (T): The time for one complete cycle. Frequency (f): The number of cycles per unit time. They are inversely related: $T = \frac{1}{f}$ .

Define displacement ( $\Delta x$ ).

The change in position; a vector quantity.

Define velocity (v).

The rate of change of displacement; a vector quantity.

Define acceleration (a).

The rate of change of velocity; a vector quantity.

Define centripetal acceleration ( $\a_c$ ).

Acceleration directed towards the center of the circle. $\a_c = \frac{v^2}{r}$

Define centripetal force ( $\F_c$ ).

Net force causing circular motion. $\F_c = m\frac{v^2}{r}$

Define work (W).

The transfer of energy by a force. $W = Fd\cos(\theta)$

Define kinetic energy (KE).

Energy of motion. $KE = \frac{1}{2}mv^2$

Define momentum (p).

Product of mass and velocity. $p=mv$ . It is a vector quantity.

Define impulse (J).

Change in momentum. $J = F\Delta t = \Delta p$ .

Define torque (<math-inline>\tau).

Rotational analog of force. $\tau = rF\sin(\theta)$

What is the effect of applying a net force on an object?

The object accelerates ( $F_{net} = ma$ ).

What happens when work is done on an object?

The object's kinetic energy changes ( $W_{net} = \Delta KE$ ).

What is the effect of an impulse on an object?

The object's momentum changes ( $J = \Delta p$ ).

What is the effect of applying a torque on an object?

The object experiences angular acceleration ( $\tau_{net} = I\alpha$ ).

What happens when the distance between two masses increases?

The gravitational force between them decreases ( $F_g = G\frac{m_1m_2}{r^2}$ ).

What happens when a spring is compressed or stretched?

It stores elastic potential energy ( $PE_s = \frac{1}{2}kx^2$ ).
