Speed
Formula for speed
speed = distance/time
Is gravity a push or pull?
It's only pull
What is acceleration?
The rate that velocity changes.
What is force?
It's simply a push or pull
When does buoyant force occur?
It occurs when an object is immersed in a fluid.
What is average speed?
Speed over a stretch of time
What is gravity?
It's a force of attraction between objects.
What does acceleration apply to?
It applies to change in speed AND direction.
What are two types of force?
Contact force and indirect force
Who discovered buoyant force?
Archimedes
On a distance-time graph, what goes on the y-axis?
The distance goes on the y-axis
Does gravity accelerate objects at different rates? True or false.
False, gravity accelerated everything at the same rate, but because of air resistance we can not see gravity in its true nature.
What does a vector have?
A vector has magnitude and direction.
What is Newton's 3rd Law?
"Whenever an object exerts a force on a second object, the second object exerts an equal and opposite force on the first."
What impacts an object's ability to float or sink?
Density
What does velocity have, but speed does not?
Velocity has a direction
What is the force of gravity on earth?
9.8
What is centripetal acceleration?
It's acceleration in a circular motion.
What is inertia?
Inertia is the tendency of all objects to resist a change in motion
What will happen to an object whose weight is equal to the buoyant force?
The object will float.
