Unit Review:  MOTION and FORCES      Study Review

Key Idea 5:    Energy and matter interact through forces that result in changes in motion.

Introduction: Examples of objects in motion can be seen all around us. These motions result from an interaction of energy and matter. This interaction creates forces (pushes and pulls) that produce predictable patterns of change. Common forces would include gravity, magnetism, and electricity. Friction is a force that should always be considered in a discussion of motion. When the forces acting on an object are unbalanced, changes in that object’s motion occur. The changes could include a change in speed or a change in direction. When the forces are balanced, the motion of that object will remain unchanged. Understanding the laws that govern motion allows us to predict these changes in motion.

Performance Indicator 5.1: Describe different patterns of motion of objects.

Major Understandings:

5.1a The motion of an object is always judged with respect to some other object or

point. The idea of absolute motion or rest is misleading.

5.1b The motion of an object can be described by its position, direction of motion, and speed.

5.1c An object’s motion is the result of the combined effect of all forces acting on the

object. A moving object that is not subjected to a force will continue to move at a con-

stant speed in a straight line. An object at rest will remain at rest.

5.1d Force is directly related to an object’s mass and acceleration. The greater the force,

the greater the change in motion.

5.1e For every action there is an equal and opposite reaction.

Performance Indicator 5.2: Observe, describe, and compare effects of forces (gravity, electric current, and magnetism) on the motion of objects.

Major Understandings:

5.2a Every object exerts gravitational force on every other object. Gravitational force

depends on how much mass the objects have and on how far apart they are. Gravity is

one of the forces acting on orbiting objects and projectiles.

5.2b Electric currents and magnets can exert a force on each other.

5.2c Machines transfer mechanical energy from one object to another.

5.2d Friction is a force that opposes motion.

5.2e A machine can be made more efficient by reducing friction. Some common ways of

reducing friction include lubricating or waxing surfaces.

5.2f Machines can change the direction or amount of force, or the distance or speed of

force required to do work.

5.2g Simple machines include a lever, a pulley, a wheel and axle, and an inclined plane.

A complex machine uses a combination of interacting simple machines, e.g., a bicycle.
