Final answer:
The force of gravity acting on a 7 kg object on the Moon would be approximately 11.375 Newtons, calculated using the Moon's gravitational acceleration of 1.625 m/s².
Step-by-step explanation:
The force of gravity acting on an object on the Moon can be calculated using the formula for gravitational force, which is F = m × g, where F is the force of gravity, m is the mass of the object, and g is the acceleration due to gravity. On the Moon, the acceleration due to gravity is about 1.625 m/s². For an object with a mass of 7 kg, the force of gravity would be:
F = 7 kg × 1.625 m/s²
F = 11.375 N (rounded to three significant figures)
Therefore, the force of gravity acting on a 7 kg object on the Moon would be approximately 11.375 Newtons (N).
