What force is responsible for pulling the skateboarder down the ramp? A Tension A B Friction B C (c) Gravitational D Applied D E Normal E

## Step 1<br />The problem is asking us to identify the force that is responsible for pulling a skateboarder down a ramp. The options provided are Tension, Friction, Gravitational, Applied, and Normal.<br /><br />## Step 2<br />Let's analyze each option:<br /><br />### Tension<br />Tension is a force that is transmitted through a string, rope, or wire when it is pulled tight by forces acting from opposite ends. In this case, the skateboarder is not being pulled down the ramp by a string, rope, or wire, so tension is not the correct answer.<br /><br />### Friction<br />Friction is a force that opposes motion. It acts in the opposite direction to the motion of an object. In this case, friction would act to resist the skateboarder's motion down the ramp, not pull them down.<br /><br />### Gravitational<br />Gravitational force is the force that attracts a body toward the center of the earth, or toward any other physical body having mass. This force is always present and acts to pull objects towards the center of the earth. In this case, the skateboarder is being pulled down the ramp by the force of gravity.<br /><br />### Applied<br />Applied force is a force that is applied to an object by a person or another object. In this case, the skateboarder is not being pulled down the ramp by an applied force.<br /><br />### Normal<br />Normal force is a force that acts perpendicular to the surface of an object. In this case, the normal force would act perpendicular to the ramp, not pulling the skateboarder down.<br /><br />## Step 3<br />Based on the above analysis, the force responsible for pulling the skateboarder down the ramp is the gravitational force.
