Work in pairs. Describe what’s going on in the picture below. Say what forces are acting on the object (the sledge).

The sledge is moving along the snow. Several forces are acting on it: the applied force pulls it forward, the frictional force acts in the opposite direction, the gravitational force pulls it downward, and the elastic force acts upward from the snow. The net force shows the overall direction of motion.

• F1 — force applied to the object
• F2 — force applied to the object
• F3 — frictional force
• F4 — gravitational force
• F5 — elastic force
• F6 — net force
