Gravity
It is the friction between the snowboard and the snow that makes it slow down.
The force that makes an object slow down and stop is called friction. Friction is the resistance encountered when one object moves in contact with another.
When you go down a slide, the main force acting on you is gravity, pulling you downward. Friction between your body and the slide surface helps to slow you down and control your speed. Additionally, there may be air resistance pushing against you as you move through the air.
The force that makes motion slow down and stop is called friction. Friction is the resistance that occurs when two surfaces come into contact with each other. It acts in the opposite direction of the motion and reduces speed.
Friction is the force that slows objects down. Especially when combined with another force, such as gravity. When you have low friction, such as on ice, you slow down much slower than when you have high friction, such as on a road.
The force that makes a parachute go up is called drag. As the parachute deploys, it creates drag by slowing down the descent of the person wearing it, leading to an upward force that helps to slow down their fall.
Friction is important on a water slide as it helps slow down the rider's speed to ensure a safe descent. Gravity, on the other hand, provides the force that pulls the rider down the slide. Together, friction and gravity work in harmony to control the speed and movement of the rider on a water slide.
A force is a push or pull that either makes the object speeds up, slow down, change direction etc.
The force that tends to slow objects down is friction. Without friction, people would slide and have difficulty walking as there would be no grip between their feet and the surface they are walking on, similar to walking on ice.
Answer #1:It could be called a lot of things, but you might just call it a push forceor an applied force to be clear.========================Answer #2:After Dad has stopped pushing and the child is in the process of sliding down,there are two real forces and one pseudo-force acting on her. I don't think anyof them has a name, but they're easy to describe:-- the gravitational force, pointing straight toward the center of the Earth;-- the normal force, pointing perpendicular to the slide outward, and equal to thecomponent of the gravitational force that's perpendicular to the slide inward;-- the pseudo-force of friction, pointing parallel to the slide, and opposite to thechild's motion;
Friction
No, force is not always needed to slow down an object. In cases where there is friction or air resistance, these forces can naturally slow down an object without the need for external force. For example, a ball rolling on a table will slow down due to the friction between the ball and the table surface.
