Label
A motorbike travels east and begins to slow down before a traffic light. In which direction is the motorbikes acceleration going?
West
Pulls objects towards the center of an object with mass
Gravity
What is the unit for force?
Newtons
m/s2 is the unit for?
Acceleration
Has magnitude but no direction
Scalar
Find Vf
Vi= -2.4 m/s
t = 3 s
a = 9.8 m/s2
27 m/s
A force that is exerted (applied) perpendicular to the surface
Normal
What is Newton's 2nd Law?
F = m*a
Net Force is?
The total amount of forces acting upon an object
What is a vector?
Has magnitude and direction
Find x
Vi= 2 m/s
a= 9.8 m/s2
t= 15 s
1122.1 m
A force that opposes motion (is the the direction opposite of motion)
Friction
What is Newton's 1st Law?
An object at rest stays at rest or an object in motion stays in motion unless acted upon by an unbalanced force
Slope Formula
y2-y1/x2-x1
On a graph, how much the numbers on your graph increase by (same amount)
Interval
An object accelerates from rest, with a constant acceleration of 4.5 m/s2, what will its velocity be after 30s?
135 m/s
A force that is exerted (applied) on an object by a person or another object
Applied
Give an example of Newton's 3rd Law
Objects exerting equal but opposite forces on each other
How do you find velocity?
Distance/time
What is acceleration?
The quantity that tells you how your velocity changes over time
Rebecca is driving a car at 20 m/s when she sees the light turn red 12 m away from her. If she slows down with an acceleration of -13 m/s2, what is their final velocity?
9.38 or 9.4 m/s
What is tension?
A pulling force transmitted across the length of an object by the means of a string, a rope, chain, or similar object
What is Newton's 3rd Law?
When two objects interact they exert forces equal in magnitude but opposite in direction on each other
What is the slope of a velocity vs time graph?
Acceleration
