What is a force?
A force is a push or pull acting on an object, resulting in a change in motion or shape.
How is FORCE measured?
Force is measured in newtons (N), which is the SI unit of force. One newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared.
What can a force affect?
A force can affect an object's motion, direction, speed, or shape. It can cause objects to accelerate, decelerate, or change their state of rest.
What are the 2 main TYPES of forces are there?
Contact and Non Contact
CONTACT forces
Forces that occur when objects are physically touching each other. Examples include friction/drag, thrust, support, and normal force.
NON CONTACT forces
Forces that act on objects without physical contact. Examples include gravitational, magnetic, and electric forces.
Forces act in ____
PAIRS, meaning that for every action, there is an equal and opposite reaction.
Result of unbalanced forces?
A change in an object’s shape or state of motion.
Result of balanced forces?
No change in the object’s shape or state of motion.
Illustration of force acting on an object.
The object is shown as a square, with a dot in the middle and arrows with labels clearly showing the forces acting upon the object as well as unbalanced or balanced forces.
How to find NET force
Same direction: ADD
Opposite directions: SUBTRACT
Vertical & Horizontal: CALCULATE SEPARATELY
Define SPEED
A measure of how much distance an object covers in a specified period of time
Define Acceleration
A measure of how quickly the speed/velocity of an object is changing over a specified period of time
Define POSITIVE acceleration
An object that is INCREASING speed
Define NEGATIVE acceleration/deceleration
An object that is DECREASING in speed
