ANSWERS
1. Weight: A. The pull of gravity, always directed downwards
2. Friction: C. Force that exists between materials in contact.
3. Normal: D. Support provided by a surface
4. Applied Force: E. A push or pull applied to an object
5. Tension: B. A pulling force existing in strings and cables
Step-by-step explanation
1. The weigth is the effect of the gravity on a body. It is directed downwards towards the center of the Earth.
2. Most surfaces of materials are rough, so there's a friction force that prevents the objects in contact from sliding from each other - for example a box on an inclined plane.
3. Normal force is always upwards perpendicular to the surface. If the surface is horizontal, then it's the opposite (unless there's a third force upon the object) to the weight.
4. An applied force can make a resting object move depending on the other force's applied or can make an object in motion stop.
5. Tension is the force that keeps the string or cable straight and helps move (or stop) the object.
