The equation for vertical motion is y = v0t + .5at2.
y is vertical displacement
v0 is initial vertical velocity
a is acceleration (in meters, normal gravitational acceleration is about -9.8 m/s/s, assuming positive y is upward displacement and negative y is downward displacement)

What does vertically upwards mean?
Vertical means straight up and down,aligned with the direction of gravity. Vertically upward means vertical in the up direction. So if you jump directly straight up that is vertically upward; when you land you are travelling vertically downward.
What does vt mean in the vertical motion formula?
it means initial upwards height times time in seconds
What does a steep straight line sloping upwards on a distance time graph indicate?
It means that as time goes on, the distance increases quickly.
What is the Effect of changing the angle of projection on the magnitude of maximum height?
Max height H = u2 sin2@ / 2g So as we increase the angle of projection, then max height too increases and its value will be just u2/2g when it is projected vertically upwards ie @ = 90 deg
What is a slope on a linear graph?
The slope is the magnitude of the line upwards or downwards, commonly referred to as "rise over run". The rise is how much the graph goes up in a certain distance, and the run is how much the graph goes over horizontally that same distance. To find the slope in that situation, you have to divide the rise by the run.
When a bullet is fired upwards vertically it gains?
When a bullet is fired upwards vertically it gains kinetic energy.
When bullet is fired upwards vertically it gains in?
inertia
Which force acts on a body thrown vertically upwards?
Gravity
What is its velocity at the highest point of a ball vertically upwards?
In that case, the velocity is zero.
What does vertically upwards mean?
Vertical means straight up and down,aligned with the direction of gravity. Vertically upward means vertical in the up direction. So if you jump directly straight up that is vertically upward; when you land you are travelling vertically downward.
How high does a rocket go?
It launches a a rocket vertically upwards with an initial speed of 40.0 m/s.
How long does it take for a ball to hit the ground if it was thrown vertically atop a 2 meter building at 15 meters per second vertically?
The answer depends on whether the ball is thrown vertically upwards or downwards. That critical piece of information is not provided!
What makes a thrown upwards body to stop for some few seconds before desendeing down?
It DOES NOT stop for a 'few seconds' . It stop only for an instant as its movement changes from upwards to downwards.
How you calculate the kinetic energy of the particle projected vertically upwards?
Use the classic formula e = 1/2 x mv2
What does it mean when there is a curved line going upwards on a graph?
When there is a curved line going upwards on a graph it means the distance is increasing
What causes the most earthquakes?
Earthquakes that causes most damage when two plates crashed and one plate moves upwards vertically than the other plate.
How much force is needed to lift 78 pounds person into the air?
Any upward force greater than 78 lbs will accelerate that person vertically upwards.
