Front

What is the definition of weight?

Back

Weight is the force exerted by gravity on an object, which is proportional to its mass.

Front

True or False: Weight is the quantity of matter contained in an object.

Back

False. Weight is the force due to gravity, not the quantity of matter.

Front

What does stress represent in a physical context?

Back

Stress represents the resulting force distribution inside a body.

Front

What type of injury occurs from a single force?

Back

An acute injury occurs when a single force causes an injury.

Front

What is the difference between acute and chronic injuries?

Back

Acute injuries occur suddenly due to a specific event, while chronic injuries develop over time due to repetitive stress.

Front

Define mass in a scientific context.

Back

Mass is the measure of the amount of matter in an object, typically measured in kilograms.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g).

Front

What is gravitational acceleration on Earth?

Back

Gravitational acceleration on Earth is approximately 9.81 m/s².

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases.

Front

What is a force in physics?

Back

A force is an interaction that causes an object to change its velocity, direction, or shape.
