Forces and Speed Flashcards
What can unbalanced forces make things do
They can make thing change speed direction shape
What are balanced forces
When two forces have equal strength
What is air resistance
Air resistance reacts on something e.g parachute creating a drag back making it slower
The faster you go the less air resistance there will be?
No, the faster you go the more air resistance
What is streamlined
A fish is streamlined so it can cut through the water easily
What does terminal velocity mean
A constant speed
How do you work out a average speed
AVERAGE SPEED= TOTAL DISTANCE TRAVELED/ TOTAL TIME TAKEN
What is friction
Friction is basically the reactant force on something that makes it stop e.g car on road
What do you measure a force
You measures it in N newtons
What is upthrust
What is pushing it up
