Front

What is momentum?

Back

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

Front

How is momentum calculated for an object?

Back

Momentum (p) is calculated using the formula p = mass (m) × 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 difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that object.

Front

How does mass affect weight?

Back

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

Front

What is the formula for calculating weight?

Back

Weight (W) is calculated using the formula 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

How does mass affect the force needed to accelerate an object?

Back

More mass requires more force to achieve the same acceleration, according to Newton's second law.

Front

What is Newton's second law of motion?

Back

Newton's second law states that force equals mass times acceleration (F = ma).

Front

If a 10 kg object accelerates at 2 m/s², what is the net force acting on it?

Back

The net force is 20 N (calculated using F = ma).
