What two things should you describe about a force that acts on an object?
the 2 things you should describe about a force that acts on an object is the size and direction
What is a situation in which an object is weightless?
When you're in space or theres no force acting on you.
Describe two effects of a force on a moving object?
slow the object down or speed it up
What term is used to describe the flow of air or fluid around an object?
The term that is used to describe the flow of air or fluid around an object is buoyant force. An example of buoyant force is when you float on an inflatable object in the swimming pool.
What must you have in a problem to adequately describe velocity?
Describe three situations in which a force changes the velocity of an object?
Can the buoyant force be less than the object's weight?
Of course. That's exactly the situation whenever an object sinks.
What is a measure of force of gravity on an oject?
When the object is in a normal every-day situation on Earth or another planet, that's the force we usually call the object's "weight".
What did Newton's second law of motion describe?
It describes how an object will react to a force.
What are all of the terms that are appropriate for a situation that produces work.?
the object moves and a force acts
Terms that are appropriate for a situation that produces work?
the object moves a force acts apex:0
Describe the effect that height has on the force and energy needed to lift an object?
Lifting an object to a greater height requires more energy, but not any more force, thanlifting it to a not-as-great height.
How the buoyant force is related to floating sinking describe how knowing the density of an object helps predict whether the object will sink or float?
