Description | Answer |
force that pulls objects towards each other | gravity |
product of an object's mass & velocity transfer of energy from one object to another | momentum |
tendency of an object to resist any change in motion | inertia |
Newton's first law states, "An object in motion will continue in motion." Why does an object stop? | friction& gravity |
What is the net force of a balanced force? | 0 |
What is the net force of an unbalanced force | greater than 0 |
WHat is the difference between weight and mass? | mass- balance weight- gravity |
Why does mass not make a difference in free fall? | all accelerate at the same rate regardless of mass |
How does gravity affect objects that are moving horizontally? | objects will hit the ground at the same time (pulls objects down) |
How is mass related to inertia | more mass greater inertia |
How is mass related to momentum? | the more mass more momentum |
What happens to the momentum of 2 objects after they collide? | energy is absorbed or transferred from one object to another |
What acceleration does all objects free fall? | 9.8 meters per second squared 32ft. per sec. squared |
occurs when a solid object moves through a fluid Examples- surfing& swimming | fluid friction |
friction that occurs when one solid surface slides over another examples- iceskating skiing | sliding friction |
friction that acts on objects that aren't moving examples- cup table | static friction |
when an object rolls across a surface examples- bicycle skateboards | rolling friction |
Newton is perhaps most famous for what? | three laws about objects in motion and the forces that act on them |
Newton's work wrote them and called them what? | Newton's laws of Motion |
Newton's first law f motion concerns | inertia |
objects that are still remain | still |
objets that are moving | continue moving with a constant velocity |
Newton's second law concerns | acceleration |
A bowling ball is more difficult to do what than a tennis ball | throw |
Newton's third law of Motion is what | the motion of action and reaction |
when you hit a baseball with an aluminum bat | the ball has another equal and opposite reaction |
Inertia lab | pennies |
Acceleration depends on | he object's mass and on the net force acting on it |
An object moving at a contsant velocity | will continue moving unless acts don by an unbalanced force |
if one object exerts the second object exerts force of equal strength in the opposite direction on the first object | 3rd law |
mass times velocity = | momentum |
the equation for newton's second law is... | forces= mass times acceleration |
golf ball lab | 3rd law-momentum |
Momentum equation is... | mass times velocity = momentum |
golf ball lab | newton's 3rd law |
rocket lab | newton's second law |
