Reflecting on the Weight of an Object
What is the weight of an object that has a mass of 25 kg on the surface of Earth?
Choices:
A. 245 N
B. 250 N
C. 2450 N
Answer:
The weight of an object that has a mass of 25 kg on the surface of Earth is 245 N.
When an object has a mass of 25 kg on the surface of Earth, its weight can be calculated using the formula:
Weight = mass x gravitational acceleration
Given that the mass is 25 kg and the gravitational acceleration on Earth is approximately 9.8 m/s^2, we can substitute these values into the formula:
Weight = 25 kg x 9.8 m/s^2 = 245 N
Therefore, the weight of an object with a mass of 25 kg on the surface of Earth is 245 N. This relationship between mass and weight showcases the effects of gravity on objects in our everyday lives.
