Newton’s 1st Law of Motion
An object in motion stays in motion (constant speed) unless acted on by another force.
Force - (N) newton, forces may be balanced or unbalanced.
Inertia
Inertia - an object’s ability to resist motion
(depends on mass), a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
A book is on a table and it will not move unless somebody exerts force on it externally.
This force has to be unbalanced (opposite force) if applied at same time, will not make the book move.
Examples of Newton’s 1st Law of Motion
The head of a hammer can be tightened onto the wooden handle by banging the bottom of the handle against a hard surface.
If you are stopped at a stop light on a level road, you need to step on the gas pedal when the light turns green to be able to go forward. Newton’s 2nd Law of Motion
If the same force is applied to an object with greater mass, the object accelerates at a slower rate because mass adds inertia.
Objects with more mass(kg) need more force (N) to accelerate. Formula for Newton’s 2nd Law of Motion
FORCE = MASS times ACCELERATION
Pushing a 10 lb ball as hard as you can, then pushing a 5 lb ball as hard as you can.
The 10 lb ball would accelerate less than the 5lb ball because the 10 lb ball has more mass.
Mike's car weighs 1,000 kg and is out of gas. Mike is trying to push the car to a gas station and he makes the car go 0.05 m/s/s. Using Newton's Second Law,
Motion Sir Isaac Newton learned a lot from his famous apple-on-the-head incident. Newton's first law of motion, also called the law on inertia, states that an object continues in its state of rest or of uniform motion unless compelled to change that state by an external force. The law appears to contain two separate statements. The first statement — a state of rest will continue unless a force is applied — seems intuitively correct. The second statement — an object will continue with a constant…
Newton’s Second Experiment Objectives: To study newton’s Second Law for a given system of masses using the computer to determine acceleration. Apparatus: Science Workshop Interface, laptop, USB drive, rod stand to raise track, dynamics cart, ±50 Newton force sensor, mass set with hanger, smart pulley with table clamp, track, string, meter stick. Procedure: Part A: In this activity, a smart pulley will measure the motion of the cart on one side that will be pulled by a string on the other side…

Newton’s Laws of Motion ❏ Define and differentiate between Newton’ s 3 Laws of motion. ❏ Describe the use of ICT in the investigation of motion. Newton’s First Law of Motion Every object continues in its state of rest or uniform motion in a straight line unless made to change by a resultant force. 1. Explain 3 examples that illustrate this law. 2. Answer Qs 1 &2 on page 23 of the text book. Investigating motion of an object using ICT Traditionally, data might have been collected using rulers…
December 3, 2014 Isaac Newton Isaac Newton was born on January 4, 1643, in Woolsthorpe, England and died in London on March 31, 1727. He was an established physicist and mathematician, and one of the great minds of the 17th century Scientific Revolution. Isaac’s father was a prosperous local farmer but died 3 month after Isaac was born. Isaac himself was born prematurely and was not expected to survive. When Isaac was 3 years old, his mother, Hannah Ayscough Newton, remarried a well-to-do…
Lab #8 Vectors and Net Forces Purpose: the purpose of this lab is to apply Newton's Second Law and to understand how forces cause objects to accelerate. We limit to motion in 1-dimension and look at the affects of varying the forces exerted on a system of objects, as well as varying the mass of the system. This lab also teaches some concepts of measurement and analysis of experimental data. Procedure: In part one performs set up of experiment and measure the time it takes the glider to travel…
Connection of Newton’s Laws of Motion Newton’s first law of motion is an object in motion stays in motion, an object at rest stays at rest unless acted upon by an outside force. When your container hits the ground it is acted upon by an outside force. An external force is required to set the egg into motion. When you fill your container with what ever material you use you are trying to get that material to absorb the difference in force between what the egg can withstand and the actual force…
Primary author: Dequan Ye Partner: Dorothy Liu Newton’s 2nd Law of Motion Introduction: We verified the Newton’s second law of motion, ∑i Fi = ma, by first holding total mass m constant and confirm the relationship between the other two variable (external force F and acceleration a), and then hold external force F constant while I verify the relationship between total mass m and acceleration a, with a set of gliders on a frictionless air track. Procedure: While we were holding total mass m constant…
Kimberly Williams (13867793) Physics Wednesday, June 26, 2013 Unit 2 Assignment 1: Newton’s Laws (Portfolio) * Describe force as it applies to linear motion. * Motion that takes place along a straight line. Mechanical energy can take the form of rotary or linear motion. The push or pull that gives energy to an object. A force changes an object's motion or state of rest. * Explain what is meant by a net or unbalanced force. * An unbalance force is one that is not opposed…
Title: Isaac Newton laws of motion in Basketball Author: Kevin B. www.livestrong.com/article/401393-isaac-newton-laws-of-motion-in-basketball/ Article Review Sir Isaac Newton was one of the greatest scientists and mathematicians that ever lived. He was born in England on December 25, 1643. He was born the same year that Galileo died. He lived for 85 years. In basketball many of his laws can be seen such as in the first law, which states that an object in motion stays in motion. Basketball…
