Motion Graphs / Ramps
In a distance-time graph, what does the slope represent?
How is distance different than displacement
distance = number of steps
displacement = final position - original position
How does large launch angle affect the range of a launched projectile?
bigger launch angle... less range but more height
refers to the degree of exactness or reproducibility of a set of measurements.
precision
This is the rate at which work is done
power
The components of gravity perpendicular to a ramp
mg*cos(theta)
The time for a horizontally fired projectile to hit the ground is the same as one that is dropped from the same height.
true
What is the x component of the launch velocity of a projectile?
VCos(theta)
Target value is 5
Data = {6,6.2,6,6.3,6}
This data has a large amount of ______ error.
systematic
A spring toy is stretched and then reaches its maximum height. What's the energy conversion here?
spring potential to gravitational potential.
What does the area under a velocity-time graph represent?
displacement
What is a value that kinematics equations do not depend on.
mass
What is the acceleration due to gravity on earth?
10
0.050017000100
This number has ______ sig figs.
11
Which of these is larger? Coefficient of static or kinetic friction?
static
What does the slope of a velocity-time graph represent?
acceleration
An object starts from rest. What is the initial velocity?
0 m/s
in the absence of air resistance the mass of an object does not affect how much time it takes for it to hit the ground.
true
0.00004345 in scientific notation is:____
4.3*10^5
flexing muscles is an example of _______ potential energy
spring
A "/" shape below the x axis on a velocity time graph means the object is
slowing down towards
An object is thrown up in the air. What is the final velocity?
0 m/s
What is the equation to find the height an angled projectile will reach?
v^2(sin(theta))^2 / (2g)
This is a value that has magnitude and direction
vector
answers cn vary but it should be at a large height
