A push or pull on an object
Total amount of force applied to an object
W=20kg * 9.8m/s² W= 196N
F=MA F= 1400 * 4.7 F= 6,580 N
Static Rolling Sliding Fluid
Gravity and air resistance
The object is no longer accelerating; force of gravity is equal to the force of air resistance
120N=60kg* a 120/60=a 20m/s²=a
An object in which the only force acting is gravity
F=MA F=30,400 * 1.2m/s² F=36,480 N
Law of Inertia
Resistance of an object to change its motion
The magnitude (strength)
The head of the arrow points in the direction of the force
Motion is unchanged if the force is balanced
The distance traveled over a certain amount time
Speed is a scalar quantity (magntude only) and velocity is magnitude and direction
The acceleration increases
The greater the mass the greater the inertia
The rougher the surface the greater the friction
300/50 T=6 hrs
Increase the mass
Reaction forces are of equal force to the action but in opposite direction
It changes the speed or direction
F=M*A F= 7 * 9.8 F=68.6 N
FORCES Mrs. Cholak.
FORCE Chapter 10 Text. Force A push or a pull in a certain direction SI Unit = Newton (N)
Warm-up 1. If a toy train has a mass of 1.5 kg & accelerates at a rate of 20 m/s2, what is the amount of force acting on it? 2. Make a Venn diagram comparing/contrasting.
Force and Gravity.
Speed Potpourri FrictionForce Acceleration
Chapter 2 – sections 1, 2, and 3 vocabulary 1.Force – a push or a pull exerted on an object 2.Unbalance force – a nonzero net force, which changes an object’s.
What is net force?.

Force : Push or pull Newton: unit to measure force Net force: combination of force Unbalance force: object start moving Balance force: object doesn`t move.
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.
Physics The study of physical forces and qualities: the scientific study of matter, energy, force, and motion, and the way they relate to each other The.
Chapter 2: Force & Newton’s Laws. What is a balanced force? Forces that are equal in size but opposite direction.
Chapter 12: Forces and Motion
Motion & Forces.
Newton’s Laws of Motion
Force = a push or a pull Mrs. Clarici
Physical Science Forces
Developed the concepts of both gravity and motion Laid the foundation for modern science Developed the 3 Laws of Motion.
