Physics Chapter 1-5 Quiz

You can use the equation $v = u + at$, where $v$ is the final velocity, $u$ is the initial velocity, $a$ is the acceleration, and $t$ is the time.

Newton's second law states that the net force $F$ acting on an object is equal to the mass $m$ of the object multiplied by its acceleration $a$, expressed as $F = ma$.

The work done $W$ can be calculated using the formula $W = mgh$, where $m$ is the mass, $g$ is the acceleration due to gravity, and $h$ is the height lifted.

<p>The gravitational force $F$ can be calculated using $F = G \frac{m_1 m_2}{r^2}$, where $G$ is the gravitational constant, $m_1$ and $m_2$ are the masses, and $r$ is the distance between their centers.</p> Signup and view all the answers

<p>The first law of thermodynamics states that the change in internal energy $\Delta U$ of a system is equal to the heat added to the system $Q$ minus the work done by the system $W$, expressed as $\Delta U = Q - W$.</p> Signup and view all the answers

<p>According to Hooke's Law, the stretch $x$ of a spring is given by $F = kx$, where $F$ is the force applied, $k$ is the spring constant, and $x$ is the stretch of the spring.</p> Signup and view all the answers

<p>Bernoulli's equation states that $P + \frac{1}{2} \rho v^2 + \rho gh = constant$, where $P$ is the pressure, $\rho$ is the fluid density, $v$ is the fluid velocity, and $h$ is the height.</p> Signup and view all the answers
