Physics Review. Day 2 (Physical Science)

Front

Specific Heat Value

Back

The amount of energy required to raise the temperature of 1 kg of a material by 1 degree Celsius.

Front

Conduction

Back

The process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or electric potential.

Front

Parallel Circuit

Back

A type of electrical circuit where there are multiple paths for current to flow, allowing for different components to operate independently.

Front

Current Calculation

Back

To find the current (I) flowing through a device, use the formula I = P/V, where P is power in watts and V is voltage in volts. For a 100 W heater plugged into a 120 V outlet, I = 100 W / 120 V = 0.83 A.

Front

Electrical Circuit

Back

A complete path through which electric charges can flow, consisting of a source of voltage, conductors, and a load.

Front

Thermal Energy

Back

The total kinetic energy of particles in a substance, which is related to its temperature.

Front

Resistance

Back

A measure of the opposition to the flow of electric current, typically measured in ohms.

Front

Voltage

Back

The electric potential difference between two points in a circuit, measured in volts.

Front

Electric Force

Back

The force exerted by charged objects on each other, which can be attractive or repulsive.

Front

Magnetism

Back

A physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.
