Benchmark Objectives•SC.5.P.13.1 – Identify familiar forces that cause objects to move, such as pushes or pulls, including gravity on falling objects. AA • SC.5.P.13.2 – Investigate and describe that the greater the

force applied to it, the greater the change in motion of a given object. AA

•SC.5.P.13.3 –Investigate and describe that the more mass an object has, the less effect a given force will have on the object’s motion. •SC.5.P.13.4 –Investigate and explain that when a force is applied to an object but it does not move, it is because another opposing force is being applied by something in the environment so that the forces are balanced.

FORCE & MOTION

What is MOTION?

• Always a change in the position of an object.• Sometimes it may involve a change in

direction, too.

What changes motion?

5

• Motion of an object changes when a force acts upon the object.

• An object remains in motion, or at rest, unless a force acts on it.

Object at rest Object in motion

What are forces?

GravityFriction

Air ResistanceA push or a pull

Balanced Forces Versus

Unbalanced Forces

Types of Motion

• Move in a straight line.• Move in a curved path.• Move back and forth.• Move at different speeds.

Measurement Tools for Motion

Speed• Distance (meter stick)

• Time (stopwatch)

Types of Forces

• Push or pull• Friction• Air Resistance• Gravity

What conditions can affect force and motion?

• Amount of mass• Type of force applied• Type of surface texture• Surface area

Moon

Earth

Factors that Determine Motion

• Amount of force• Mass of the object• Change in speed

(acceleration)
