Physics Honors - 2nd Quarter Review

Front

What is the difference between mass and weight?

Back

Mass refers to the amount of matter that an object contains; weight refers to how heavy an object is due to the force of gravity.

Front

How do you calculate frequency from the number of spins and time?

Back

Frequency (Hz) = Number of spins / Time (s). For example, a ceiling fan spins 600 times in 20 seconds, so frequency = 600 / 20 = 30 Hz.

Front

What characterizes a perfectly inelastic collision?

Back

In a perfectly inelastic collision, two objects collide and stick together, moving as one mass after the collision.

Front

What did Galileo discover about pendulums?

Back

Galileo discovered that the only thing that matters is the length of the string for the period of a pendulum.

Front

How do you calculate the reindeerpower produced by Rudolph's jump?

Back

To find the reindeerpower, use the formula: (mass * gravity * height) / time, then divide by 746.

Front

What is the formula for gravitational potential energy?

Back

Gravitational potential energy (PE) = mass (m) * gravity (g) * height (h).

Front

What is the principle of conservation of momentum?

Back

The total momentum of a closed system remains constant if no external forces act on it.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object moves, while velocity is a vector quantity that includes direction.

Front

What is Newton's second law of motion?

Back

Newton's second law states that Force (F) = mass (m) * acceleration (a).

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 0.5 * mass (m) * velocity (v)^2.
