Presentation transcript:

FORCES An object’s motion is the combined affect of all forces acting on an object

Forces  Force is any push or pull Examples of forces:  Friction  Gravity  a person spiking a volleyball

Balanced Forces  Objects at rest Objects that move in a straight line at constant speed

Examples of Balanced Forces Objects at rest Objects that have reached terminal velocity

Unbalanced Forces  Objects speeding up  Objects slowing down  Objects changing direction

Examples of Unbalanced Forces Objects speeding upObjects Slowing Down

Examples of Unbalanced Forces Objects Changing DirectionObjects Moving in a Circle
