AP Physics 1 Final Exam Review

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

How do you calculate the height from which an object falls using kinetic energy?

Back

Height (h) can be calculated using the formula h = KE / (mg), where KE is kinetic energy, m is mass, and g is the acceleration due to gravity (approximately 9.81 m/s²).

Front

What is the formula for gravitational force between two objects?

Back

The gravitational force (F) is calculated using Newton's law of universal gravitation: F = G(m₁m₂)/r², where G is the gravitational constant, m₁ and m₂ are the masses of the objects, and r is the distance between their centers.

Front

What factors affect gravitational attraction?

Back

Gravitational attraction is affected by the masses of the objects and the distance between them.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What happens to the velocity of an object in free fall?

Back

In free fall, the velocity of an object increases uniformly due to the constant acceleration of gravity.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate over time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the formula for calculating total resistance in a series circuit?

Back

In a series circuit, total resistance (R_total) is the sum of all individual resistances: R_total = R₁ + R₂ + R₃ + ...

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R): V = IR.
