Physical Science Semester 1 Review

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, expressed as p = mv.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula: p = mass (m) x velocity (v).

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg*m/s).

Front

What is the relationship between wavelength and frequency of light?

Back

The frequency (f) of light is inversely proportional to its wavelength (λ), given by the equation: v = c/λ, where c is the speed of light.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated using the formula: KE = 1/2 mv².

Front

What is the unit of kinetic energy?

Back

The unit of kinetic energy is Joules (J).

Front

How do you calculate kinetic energy?

Back

Kinetic energy (KE) is calculated using the formula: KE = 1/2 mass (m) x velocity (v) squared (v²).

Front

What is the formula for force?

Back

Force (F) is calculated using the formula: F = mass (m) x acceleration (a).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

What is the unit of force?

Back

The unit of force is Newton (N).
