Specific force

Imagine you're sitting in the backseat of a car and the car starts moving. You feel yourself being pushed back against the seat. That's because of a force called "specific force."

Specific force is the force that pushes or pulls something in a specific direction. It's like when you push on a toy car and it starts moving. That's because you applied a specific force to it.

In space, where there is no gravity or air, astronauts can experience specific force. When they move around, or when their spacecraft speeds up or slows down, they can feel themselves being pushed in different directions.

So remember, specific force is the force that makes things move in a certain direction, like when you push a toy car or feel yourself being pushed back in your car seat.
