the force exerted by a weightlifter holding a mass of 180kg above the ground

To calculate the force exerted by a weightlifter holding a mass of 180 kg above the ground, we can use Newton's second law of motion. The force due to gravity on an object is given by the formula:

\[
F = m \cdot g
\]

where:
- \( F \) is the force in newtons (N),
- \( m \) is the mass in kilograms (kg),
- \( g \) is the acceleration due to gravity, which is approximately \( 9.81 \, \text{m/s}^2 \) on Earth.

Now, substituting the given values:

\[
F = 180 \, \text{kg} \times 9.81 \, \text{m/s}^2
\]

Let me calculate this.The force exerted by the weightlifter holding a mass of 180 kg above the ground is approximately **1765.8 newtons (N)**.

Here are 5 related questions:
1. How does the force change if the mass increases or decreases?
2. What is the difference between weight and mass?
3. How does the force change on other planets with different gravity?
4. What would be the force if the weightlifter was on the moon?
5. How does acceleration due to gravity affect everyday objects?

**Tip:** Always remember that weight is the force exerted by gravity on an object and depends on both the object's mass and the local gravitational field.
