What force pushes a car backwards?
Air resistance
What force pushes a car down?
Weight
What force pushes a car up?
Reaction force.
What force pushes the cars wheels back?
Friction
What is the force “weight”?
A force created by gravity attracting an object
What is the force “air resistance”?
An opposing force created when an object has to move through air.
What is the force “upthrust”?
A force that pushes an object up when it is in liquid.
What is the force “friction”?
Force created when to objects rub together.
What is the force “push/pull”?
A force when an object is moved either forward or backwards.
Which way does the engine move the car?
Forwards (mostly)
What speed does a car go when both “air resistance” and “driving force” the same.
A constant speed
When a car is slowing down what are the two strongest forces?
Air resistance and friction.
Which force always goes against moving objects?
Friction
Which force slows down objects which are moving through air?
Air resistance
