The Affect of Forces on Motion5-5.1
A push or a pull
What forces can affect motion?
Magnetism Gravity Friction
What are the four ways that force can affect motion?
Slow things down, Speed things up, Stop things Change their direction
A force that acts at a distance and cannot be seenA force that acts at a distance and cannot be seen. It comes from the furthest regions of the Earth.
Materials that have magnetic force
Poles that are the same – S to S and N to N . . .
Opposite poles – S to N and N to S will . . .
What happens to magnetic forces when they get closer?
THE GET STRONGER
Where is the greatest strength of magnetic forces on a magnet?
AT THE POLES
A pull that attracts one object to another
When do you notice this attraction of one object to another?
WHEN THE OBJECT IS BIG like a pencil to the Earth
What does the attraction of the Moon cause on the Earth?
How does the Sun’s gravity affect the Earth?
KEEPS IT REVOLVING
The force that opposes motion when surfaces are touching
How can you make more friction?
MORE MASS Rougher Surfaces
How can you reduce the affect of friction?
LUBRICATION or ROLLERS
In which states of matter does friction occur?
SOLIDS LIQUIDS and GASES
FORCES AND MOTION CREATED BY PHYLLIS WILLIAMS. WHAT IS A FORCE? It is a push or pull. Forces can make things move faster, slower, stop, or change direction.
SCIENCE PASS REVIEW FORCE & MOTION Brooke Ard| 5 th Grade Math & Science | Griggs Road Elementary.
Mrs. E5 th Grade Force and Motion. Force – push or pull a force always acts in a certain direction ex. if you push something, the force is in the direction.
What is Force? A force is a push or pull that causes an object to move faster or slower, stop, change direction, or change size or shape. Without force,
Forces and Motion.
Forces and motions I understand what causes and what stops motions on the planet Earth
Forces Pages 188 to 191. Forces Force - a push or a pull, measured in Newtons (N) Contact Force – is a push or a pull one object applies to another object.

Balanced and Unbalanced Forces

Everyday Forces BY MR. V. CALZADA & MRS. SWANSON.
FORCE AND MOTION GARNER 5 th Grade Science 5.6D.
FRICTION AND GRAVITY. Two factors that affect the strength of friction- How hard the surfaces push together. The types of surfaces involved.
Forces are contact forces or field forces. When two bodies are in contact with each other, contact forces can result e.g. friction, twisting, pulling.
Chapter 2: The Laws of Motion
A push or a pull on an object is called a force.
Forces and Motion Unit F Ch. 1.
Forces & Motion. Motion A change in the position of an object Caused by force (a push or pull)
Unit F, Chapter 1, Section 1 pF6-11
FORCE AND MOTION REVIEW FOR UNIT TEST. 1.Earth and everything on it are affected by FORCES. 2.A force is a PUSH OR A PULL that causes an object.
Chapter 9 Forces Lesson 1 Types of Forces.
The Laws of motion.
Forces, Friction, and Gravity
FORCE AND MOTION.
Friction & Gravity Standard Analyze the effects of friction & gravity on the speed & direction of an object.
Types of Forces Gravity and Friction. Forces!!!!! PUSH Or A Pull.
Forces Force – any push or pull acting on an object
Name of Force DefinitionExamples Gravity Gravity is a force that attracts bodies of matter toward each other. It is a force that is everywhere there.
Unit 1 AMSTI: Forces & Motion
Contact and non-contact Forces
Review A force is any push or ____________.
Friction & Gravity.
Motion and Forces Force A push or a pull *Cause an object to start moving, stop moving, or change direction.
Force and Gravity.
Gravity is a force that always attracts or pulls objects toward each other without direct contact. Objects on Earth are pulled toward the center of Earth.
Chapter 12: Forces and Motion
Forces & motion 2012.
Friction When two surfaces rub together, the irregularities of one surface The force that one surface exerts on another Friction acts in a direction.
Chapter 16 Notes. Objectives 1. Describe the effects of gravity, friction, and centripetal force. 2. Explain the difference between weight and mass. 3.
FORCES Lesson 1 Friction and Gravity. What is a Force? (p.44) A push or a pull on an object in a particular direction.
Forces. What is a Force? A force is a push or a pull. To tell about a force, you must tell how strong the force is. The SI unit for the strength of a.
KS4 Physics Forces.
Gravity and Inertia.
FORCE & MOTION. Force & Motion I. Force A. Def. – a push or pull B. Measured in Newtons (n) – by a spring scale.
* An object’s change in position relative to a reference point. * Without a reference point we are unable to see motion.
