Answer 1

1. **Weight Calculation Formula**:
The formula to calculate weight (force due to gravity) is:
\[ F_g = m \times g \]
where:
- \( F_g \) = weight (in newtons)
- \( m \) = mass (in kilograms)
- \( g \) = acceleration due to gravity (approximately \( 9.81 \, \text{m/s}^2 \) on Earth)


2. **Mass Calculation Formula**:
The formula to calculate mass can be derived from the weight formula:
\[ m = \frac{F_g}{g} \]
where:
- \( m \) = mass (in kilograms)
- \( F_g \) = weight (in newtons)
- \( g \) = acceleration due to gravity


3. **Acceleration**:
When we consider acceleration, it typically involves changes in velocity. The following are the conditions that indicate acceleration:
- **Speeding up**
- **Slowing down**
- **Changing directions**

**Note**: Being at rest or moving at constant speed does not constitute acceleration, as there is no change in velocity in either situation.


4. **Example of Constant Speed**:
An example of something traveling at a constant speed is a car cruising on a highway at a speed of 60 km/h without changing speed or direction.
