Motion
a change in position
What is Motion?
how fast something moves or the distance it moves, in given amount of time
What does speed measure?
the rate at which velocity changes
What is acceleration?
Issac Newton
Who created Newton's three laws of motion?
movement
What is momentum?
reference point
What does the motion depend on?
Formula for speed
Speed= distance/time
how an objects position changes over time
what is acceleration used to determine?
Objects at rest tend to stay at rest, and objects in motion tend to stay in motion, unless acted upon by an unbalanced force
Newton's first law
transfer
when moving things run into each other, momentum can -----
reference point
What is used to describe the motion of the object?
the total distance traveled by the object divided by the elapsed time to cover that distance
What is average speed?
positive acceleration
acceleration in the same direction the object is moving, increasing speed of object
The acceleration of an object is direct proportional to the net force and inversely proportional to the mass of the object
Newton's 2nd law
moving
Whenever something is ----, it has momentum
the location of the place or object
What is the position of a place or object?
scalar
What kind of quantity is speed?
negative acceleration
acceleration opposite to thee motion; the speed of the object decreases
For every action there is an equal and opposite reaction
Newton's third law
a heavier ball
distance and direction
What can you use to describe the position of an object?
constant speed
constant speedWhen the speed of an object remains the same- it does not increase or decrease- we say it's moving at a -------
Acceleration = final velocity- initial velocity/ time taken
What is the formula for acceleration?
The force that is exerted on an object
What are action forces?
mass
The faster something is going or the more it weighs, the more ---- it has, the more momentum it has
