Inverse proportionality graph
Equation: conservation of energy
KEf + PEf = KEi + PEi
When there is a transfer of energy to a projectile, how does the projectile’s mass affect its velocity and range?
A heavier object will have less initial velocity and less range.
Does air resistance affect x or y velocity?
both x and y velocities
What does an 1H NMR J-value represent?
the distance between adjacent spikes within a peak
Equation: kinetic energy
KE = (1/2)mv2
If an object has 0 y-velocity, what determines its length of time in flight?
height
What is the maximum value for gravitational potential energy?
0
True/False: an object cannot accelerate if it is moving at a constant speed
False: it can maintain a constant speed but change directions
Which type of collision generally imparts a bigger change in momentum to colliding objects?
elastic
Any time an object moves in a circular path, what is the net force equal to?
centripetal force
Backspin has what effect on a ball’s direction?
It causes the ball to rise.
On a velocity v. time graph, what does the area under the curve represent?
displacement
Are halogens added or subtracted when calculating units of unsaturation?
subtracted
What is deuterium?
2H: hydrogen has an extra proton (“heavy” hydrogen)
