PHYSICS: Final Course Exam Review

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up), negative (slowing down), or zero (constant speed).

Front

Define Specific Heat.

Back

Specific Heat is the amount of energy required to raise the temperature of 1 kilogram of a substance by 1ºC.

Front

What happens to the moment of inertia when an object moves closer to the axis of rotation?

Back

The moment of inertia decreases as the object moves closer to the axis of rotation.

Front

How does current behave in a series circuit when resistance decreases?

Back

The total current increases when the total voltage stays the same and circuit resistance decreases.

Front

What is the focal length of a lens that can form real images?

Back

The focal length is positive for a lens that can form real images.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t).

Front

Explain the concept of kinetic energy.

Back

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

Front

What is the relationship between voltage, current, and resistance in an electrical circuit?

Back

Ohm's Law states that Voltage (V) = Current (I) x Resistance (R).

Front

Define moment of inertia.

Back

Moment of inertia is a measure of an object's resistance to changes in its rotation, depending on the mass distribution relative to the axis of rotation.

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.
