Look at the pictures of the cars. Which car will have the most air resistance force acting upon it? They will be moving at the same speed.
All will have equal air resistance force.
What is Air Resistance
The force of water
The force that opposes the motion of objects falling through the Earth's atmosphere

What is upthrust force?
An upward force exerted by fluids on an object.
An downward force exerted by fluids on an object.
Why do boats float?
The material they are made up of.
Their volume gives them a large density.
upthrust
The number of passengers is not too high.
Which will result in the object floating?
When the upthrust force is greater than the force of gravity
When the upthrust force is equal to the force of gravity
When the upthrust force is less than the force of gravity
