There is a standard way to proceed.knewman55 said:
Acceleration is the rate of change of an object's velocity. In a force problem, it refers to how quickly an object's speed or direction is changing due to the application of a force.
To find acceleration in a force problem, you can use the formula a = F/m, where a is the acceleration, F is the force applied, and m is the mass of the object. Alternatively, you can use Newton's second law, which states that the net force on an object is equal to its mass multiplied by its acceleration.
The standard unit of acceleration is meters per second squared (m/s^2). However, it can also be measured in other units such as feet per second squared (ft/s^2) or kilometers per hour squared (km/h^2).
Acceleration can either speed up, slow down, or change the direction of an object's motion. If an object has a positive acceleration, it is speeding up, while a negative acceleration means it is slowing down. A change in direction is indicated by a change in the object's velocity vector.
According to Newton's first law of motion, an object at rest will remain at rest and an object in motion will continue moving in a straight line at a constant speed unless acted upon by an external force. Therefore, an object cannot have acceleration without a force acting on it.
