Force (F) = Mass (m) x Acceleration (a)
To find the acceleration, rearrange the formula:
Acceleration (a) = Force (F) / Mass (m)
Here's how it works:
1. Identify the force: Determine the force acting on the object. This could be gravity, friction, tension, or any other force. Make sure you have the magnitude and direction of the force.
2. Identify the mass: Determine the mass of the object in kilograms (kg).
3. Plug the values into the formula: Substitute the values for force and mass into the rearranged formula: a = F / m.
4. Calculate the acceleration: Solve the equation to find the acceleration. The acceleration will be in meters per second squared (m/s²).
Example:
Let's say a 5 kg object is pushed with a force of 20 Newtons (N). To find the acceleration:
* Force (F) = 20 N
* Mass (m) = 5 kg
Acceleration (a) = Force (F) / Mass (m) = 20 N / 5 kg = 4 m/s²
Therefore, the object will accelerate at 4 meters per second squared.
Key Points:
* Force is measured in Newtons (N).
* Mass is measured in kilograms (kg).
* Acceleration is measured in meters per second squared (m/s²).
* This formula works for objects moving in a straight line. For objects moving in a curved path, you need to consider centripetal acceleration.
