Scientists and Engineers Analyze Forces to Predict Their Effects on Movement

Forces All Around Us!; What Are Forces?; Why Study Forces?; Gravity: The Earth's Pull; Friction: Opposing Motion; Normal Force: Support from Surfaces; Applied Force: Your Push or Pull; Air Resistance: Friction in the Air; Tension: Pulling Through Ropes; Magnetic Force: Invisible Attraction; Electric Force: Charges Interact; Buoyant Force: The Floating Feeling; Balanced Forces: No Change in Motion; Examples of Balanced Forces; What Balanced Forces Do; Unbalanced Forces: Motion Changes; Examples of Unbalanced Forces; What Unbalanced Forces Do; Net Force: The Overall Effect; Force Magnitude: How Strong?; Force Direction: Which Way?; Forces in the Same Direction; Forces in Opposite Directions; Predicting Movement: Our Tools; Be an Engineer: Design with Forces!
