What do you think you need to do to make a moving object stop or slow down?
1 answer
To make a moving object stop or slow down, you need to apply a force that is opposite in direction or opposite in the direction of motion. This force is called friction or drag. Friction is a force that opposes motion and arises when two surfaces are in contact with each other. It can be increased by making the surfaces rougher, or by increasing the amount of force applied. Drag is the force that opposes motion when an object moves through a fluid like air or water. It can be increased by increasing the surface area of the object or by increasing the speed it moves through the fluid.
