Things fall to Earth because of ______________.
It would be hard to skate on a gravel road because the gravel increases ___________.
To measure speed you need to measure _______ and _______.
Time and Distance
The force of _________ can slow things down.

BATTLE OF THE BOOK Subject: SCIENCE Twenty Questions
Chapter 2.3 & 3 Force, Mass and Acceleration Newton’s Laws.
Gravity The force that pulls objects towards each other – a force of attraction between objects! On Earth, gravity is pulling everything straight down.
Gravity Unit F, Chapter 1, Section 1 pF6-11. Forces Make Things Move Force: push or pull – Act of objects – Often affect motion of objects Cause objects.
Friction and Gravity. What is Friction? Friction is the resistance to the sliding, rolling, or flowing motion of an object due to its contact with another.
Unit nd law An object will accelerate if an unbalanced force is applied to it. Its acceleration will depend on the size of the force and the mass.
Chapter 3 Force, Mass and Acceleration Newton’s Laws.
Chp 3 Newtons Laws of Motion. Force A force is a push or a pull or any action that has the ability to change motion. An object DOES NOT have to move when.
FORCE. Force A push or pull one thing exerts on another.
What is motion? An object is in motion when it’s distance from another object changes. What is a reference point? It is an object or place used to determine.
FORCE AND MOTION Mrs. Hicks Science 6 th Grade. The force that results from two surfaces rubbing against one another. VOCABULARY: ACCELERATION EQUILIBRIUM.
GravityGravity 8th Grade Investigation 7 Force and Motion.
ForceForce 8th Grade Force and Motion. Force When you push on an object, you are exerting a force on that object. Force: a pushing interaction between.
What is energy? Energy measures the ability for things to change themselves or to cause change in other things. A joule (J) is the S.I. unit of measurement.
Chapter: Forces and Changes in Motion Table of Contents Section 3: The Laws of MotionThe Laws of Motion Section 1: Motion Section 2: Forces and MotionForces.
Describing Motion Newtons Laws. First we need to define the word FORCE: The cause of motion (what causes objects to move) Two types of forces –Pushes.
Chapter 8 Motion and Forces. Reference Frame Clues are often given by looking at other objects in your surroundings Clues are often given by looking at.
Why do objects keep moving without being pushed or pull? Objects keep moving without being pushed or pulled is the Newton's first law.Another reason an.
Sir Isaac Newton 1642 – 1727 Laws of Motion Potential Energy stored energy Kinetic Energy Energy in motion.
Chapter 6 NEWTON’S 2 ND LAW Unbalanced Force Causes Acceleration.
Distance: describes how far an object has moved, regardless of its direction ex: 40km east + 25km west = 65 total km traveled Displacement: describes.
The Affect of Forces on Motion A push or a pull.
1 1 Force and Pressure. 2 What are Forces? A push or pull.
CH 3—Forces. Force, Mass, and Acceleration For any object, the greater the force is that’s applied to it, the greater its acceleration will be. The acceleration.
Chapter 6: Motion & Force. What you should know: Changes in motion and position can be measured. The types of forces that act upon an object can be predicted.
Motion and Force A. Motion 1. Motion is a change in position 2. Reference points are necessary.
Activity 76 Follow-up Is there a correlation between cart speed and block movement? Did the collision at different cart speeds last for different lengths.
The Force and Related Concepts. Force Can you define it? Definition: The cause of acceleration, or the change in an object ’ s velocity (or the push or.
