Unit 1 - Final Flashcard

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) is calculated using the formula a = F/M, where F is the net force applied and M is the mass of the object.

Front

How is weight defined in physics?

Back

Weight is defined as the measure of the force of gravity acting on an object, typically expressed in newtons (N).

Front

What is the difference between mass and weight?

Back

Mass is a measure of the amount of matter in an object and does not change regardless of location, while weight is the force exerted by gravity on that mass and can change depending on the gravitational field.

Front

What is the correct prefix for 10^9?

Back

The correct prefix for 10^9 is 'giga-'. For example, 1 gigabyte (GB) is equal to 10^9 bytes.

Front

What is the formula for average speed?

Back

The formula for average speed is Average Speed = Total Distance / Total Time.

Front

What units are commonly used to measure force?

Back

Force is commonly measured in newtons (N) in the International System of Units (SI).

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = M * a).

Front

What is the significance of the gravitational constant (G)?

Back

The gravitational constant (G) is a key quantity in Newton's law of universal gravitation, which describes the strength of the gravitational force between two masses.

Front

How does gravity affect weight?

Back

Weight is directly affected by gravity; as the gravitational force increases, the weight of an object also increases, and vice versa.

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have only magnitude (e.g., speed, distance), while vector quantities have both magnitude and direction (e.g., velocity, force).
