Ibrahim is learning about mass and weight. He understands that mass is the amount of matter in an object, while weight is the force of gravity on that object. On Earth, what is the weight of a 50 kg object? (Take g = 10 m/s²)

Khalid is learning about momentum. He understands that momentum is the product of mass and velocity. If a 5 kg object moves with a velocity of 4 m/s, what is its momentum?

George is learning about Newton's second law of motion. He understands that force equals mass times acceleration (F = ma). If a 10 kg object is accelerated at 2 m/s², what is the force acting on it?
