The speed and direction of an objects motion Acceleration The measure of how quickly the velocity of an object changes Force A push or pull on an object. Has both size and direction. Arrows are used to show the size and direction. It can change an objects speed and the direction in which...
Applied Force A force applied to an object by a person or another object. Can be balanced or unbalanced. Balanced Forces Forces acting on an object that are opposite in direction and equal in size. No change in position, direction of motion or speed of an object. Unbalanced forces Fnet Opp...
What is Force and Motion? Force = Any push or pull on an object Inertia = An object in motion will stay in motion unless another force is applied to it Friction = A force that acts against moving objects rubbing against them to slow them down Newton = A measure of force Gravity = Ano...

According to the Chinese tradition and formally posited by Feng Shui, the cosmos mirrors the five elements. Consequently, the duality in meaning can be 11 12 understood by the cyclical motion of the colours as they vary in shade and intensity. Red The most auspicious and popular colour in ...
on a body in order to change body’s state of rest or motion. has magnitude and direction. NET FORCE combination of all forces acting on an object. BALANCED FORCES Objects either do not move or move at constant velocity. UNBALANCED FORCE any change in an object’s state of motion or ...
Unbalanced forces: Change the motion of an object! Force: Push or pull! Unbalanced forces: Change the motion of an object! Maybe stopping an object from moving or putting an object in motion Balanced Force: Forces are equal and opposite to each other! Also called F surface F Normal F Grav...
NEWTON’S FIRST LAW LAW OF INERTIA An object at rest stays at rest and an object in motion stays in motion until acted on by a net external force. NEWTON’S SECOND LAW The force on an object equals the mass of the object times the acceleration of the object. In other words, a force...
Force and Friction What is Force? A force is a push or pull that acts on an object A force can cause a resting object to move, or it can accelerate a moving object by changing the object’s speed or direction Measuring Force: We measure force by using a unit called Newtons (N) Meas...
