Forces (YH)
What are the effects of a force?
A force can start or stop the motion of an object
change the size or shape of an object
increase or decrease the speed of an object in motion
Change the direction of motion of a moving action
what is friction?
Friction opposes motion.
Friction produces heat
Friction between rougher surfaces is greater
how can we reduce friction?
Lubricants
rollers, ball bearings, wheels
streamlined body shapes
What is elastic spring force?
Elastic objects change shape when a force acts on them, and return to their original shape once the force is removed
When an elastic object is stretched or compressed, it exerts a force on the object stretching/compressing it
Springs are elastic
elastic spring force is very useful in our daily lives
mattresses
clothes peg
spring balances
What are the different types of forces?
Objects are in contact
Frictional Force
Elastic spring force
objects are at a distance apart
Magnetic force
Gravitational force
what is gravitational force?
gravity is the force of attraction that exists between things that have mass.
gravity depends on the mass and distance of and between the objects
weight
the amount of gravitational force acting on an object
What is a force?
A force is a push or pull.
What is magnetic force?
the magnetic force of attraction and repulsion
