Answer:
Step-by-step explanation:
**Momentum** in physics is a measure of the motion of an object. It is a vector quantity, meaning it has both magnitude and direction. Momentum is calculated by multiplying an object's mass (m) by its velocity (v).
The formula for momentum is:
\[Momentum (p) = \text{Mass (m)} \times \text{Velocity (v)}\]
Where:
- **Momentum (p)** is measured in kilogram-meters per second (kg·m/s).
- **Mass (m)** is the mass of the object in kilograms (kg).
- **Velocity (v)** is the velocity of the object in meters per second (m/s).
Here's an example to illustrate momentum:
Suppose you have a soccer ball with a mass of 0.5 kilograms (kg) moving at a velocity of 10 meters per second (m/s). To calculate its momentum, you would use the formula:
\[p = m \times v\]
\[p = 0.5 kg \times 10 m/s = 5 kg·m/s\]
So, the momentum of the soccer ball is 5 kg·m/s. This means that the soccer ball possesses 5 units of momentum in the direction of its motion. If the soccer ball were to change its speed or direction, its momentum would also change accordingly.
