Why do physical objects move? by Julia Frankowicz III A
Bodies move towards each other.
The smooth surface, in contrast to the hard one, makes it easier for an object to move…
In physics, force is defined as the rate of change of the momentum of the body.
Experiment with air-cushion
Experiment with glass vacuum tube.
Force is an influence that causes an object to accelerate. In this case, the sum of all forces acting on the body caused its rotation.
The Principle of Inertia is a fundamental principle of classical physics.
Principle of Inertia - Experiments
The classic whip-off the tablecloth trick
Greetings to the academic staff for the brilliant performance
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.

5 Newtons Laws of Motion 5-1 Force and Mass Question: How is acceleration induced? Δv/Δt V=20 m/s wall V=5 m/s V=-5m/s V=0 Baseball: Force; influence that.
Gravity The force that pulls objects towards each other – a force of attraction between objects! On Earth, gravity is pulling everything straight down.
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.
Angular Quantities Correspondence between linear and rotational quantities:
Chapter 12 - Forces 1- Newtons First and Second Laws 2- Gravity 3 - Newtons Third Law.
FORCE Mr. Skirbst Physical Science Topic 04. What is force?
From Looney Tunes Movie Collection, Warner Bros. Entertainment, 2005.
Freefall Motion Notes Any object near the surface of the Earth experiences the pull of gravity. If released from rest, the object will fall freely toward.
Why dont action-reaction forces cancel each other? Defining Systems.
Newtons Laws of Motion Forces. Newtons First Law of Motion What happens to a ball rolling along the ground? What happens to a ball rolling along the ground?
Laws of Motion. Newton s First Law an object at rest remains at rest and an object in motion maintains its velocity (stays in motion) unless it experiences.
What causes motion?. Sir Issac Newton Developed laws of motion by age 24.
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.

Gravity: A force with which to be reckoned.. Balanced vs. Unbalanced Forces Force = the cause of acceleration or change in velocity. Net Force = combination.
Labelling Forces Correctly!. What were the names of the forces you had on your vocabulary cards last week? This can be any driving force, it may be a.
A new way of multiplying two vectors is introduced in this chapter. What is it called? A. Dot Product B. Scalar Product C. Tensor Product D. Cross Product.
Air Motions Geology 390 WSUV Dr. Robert M MacKay.
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.

Year 10 Pathway C Mr. D. Patterson 1. Define work as the product of pushing an object (F) over a distance (s) Solve problems using W = Fs = mas 2.
Aim: What are Newtons 1 st and 3 rd Laws of Motion? Do Now: What is the weight of the box? m = 20 kg F g = mg F g = (20 kg)(9.8 m/s 2 ) F g = 196 N.
