Label the forces in a free-body diagram of a box on a horizontal surface being pushed to the right with friction.
1: Weight (downward), 2: Normal Force (upward), 3: Applied Force (right), 4: Friction (left)
Label the forces in a free-body diagram of an object suspended from a rope.
1: Weight (downward), 2: Tension (upward)
Label the forces in a free-body diagram of a block sliding down an inclined plane with friction.
1: Weight (downward), 2: Normal Force (perpendicular to the incline), 3: Friction (up the incline)
Label the forces in a free-body diagram of a box at rest on an inclined plane.
1: Weight (downward), 2: Normal Force (perpendicular to the incline), 3: Static Friction (up the incline)
Label the forces in a free-body diagram of a projectile in motion (ignoring air resistance).
1: Weight (downward)
Identify the forces acting on the box in the Free Body Diagram.
1: Weight (Force of Gravity), 2: Normal Force, 3: Applied Force, 4: Force of Friction
What is a vector?
A quantity with both magnitude (size) and direction.
What is a force?
A push or pull; a vector with magnitude and direction.
What is a Free-Body Diagram (FBD)?
A diagram showing all the external forces acting on an object.
What is the magnitude of a force?
The strength or size of the force.
Define 'Resultant Force'.
The sum of all force vectors acting on an object.
What are action-reaction pairs?
A pair of equal and opposite forces resulting from the interaction between two objects, as described by Newton's Third Law.
