Motion And Newtons Laws Flashcards
How does inertia affect motion
Inertia resists change so more inertia means less change in motion
Will inertia of an object cub age if it goes to the moon
No objects will stay in motion unless acted on by another force sense gravity affects weight not the mass
What does inertia affect
Mass
What does gravity affect
Weight
What is the formula for speed
Speed=d/t
What is the formula for finding average speed and
Total distance/ total time
What does constant acceleration look like on a d T graph
Curving up
What does constant velocity look like on a d t graph
Straight increasing line
Or straight horizontal line
What does constant velocity look like on a s t graph
just straight horizontal line
What does constant positive acceleration look like on
Straight increasing line
How does a dot and arrows map show constant acceleration
By the dots space doubling in size each time, accelerating the same constant speed
Distance formula
D=s X t
What is a vector quantity
A quantity that includes magnitude and direction
What are two examples of vector quantities
Velocity and force
How is inertia related to mass
More mass equals more inertia
What is velocity
Speed in a direction
What is Newton’s first law motion
Law inertia, objects at rest tend to stay at rest, objects in motion to stay in motion unless acted on by an outside force
What is net force
Combination of all force vectors
What types of motion will have net forces of zero
At rest, balenced, constant velocity
What is support force
The force acting against gravity, normal force
What formula is given by Newton’s second law
Force= m X a
The acceleration due to gravity is
10/m/s/s
How are acceleration and net force related
When force increases so does acceleration
How is mass of an object related to its acceleration
When mass increase
Acceleration decrease
Curving down slope
