Types of force Flashcards
What are the different types of forces?
-Gravitational force
-Reaction force
-Friction
-Drag
-Air resistance
-Thrust
-Upthrust
-Electrostatic
-Magnetic
-Tension
What is an example of gravitational force?
When a football is kicked, gravity pulls it towards the center of the earth
What is an example of reaction force?
When the football lays horizontally on the pitch the grass exerts a push reaction force vertically upwards on the ball
What is an example of friction?
When a box is pushed across a carpet, the carpet exerts a frictional force, slowing it down
What is an example of drag?
When a pebble is thrown into water, water molecules flow against its solid surface, slowing it down
What is an example of air resistance?
When a skydiver opens their parachute, air resistance oposses their motion and slows them down.
What is an example of thrust?
The engine of a car exerts thrust, allowing the car to move forwards
What is an example of upthrust?
A ball held underwater when released will have upthrust, propelling it up and out of the water
What is an example of tension?
When 2 people pull on a rope at the same time
