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 potential energy as it rises due to the increase in its height above the ground. This potential energy is converted into kinetic energy as the bullet falls back to the ground. The total mechanical energy of the bullet remains constant neglecting air resistance.
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.
Why a rocket moves vertically upwards?
A rocket moves vertically upwards by expelling high-speed exhaust gases out of its engines, in accordance with Newton's third law of motion. This action generates a force in the opposite direction, propelling the rocket upwards against the force of gravity. The rate of acceleration is determined by the mass of the rocket and the force produced by the engine.
How high does a rocket go?
It launches a a rocket vertically upwards with an initial speed of 40.0 m/s.
Which force acts on a body thrown vertically upwards?
The force acting on a body thrown vertically upwards is gravity. Gravity pulls the body back towards the ground, causing it to slow down and eventually stop at its highest point before falling back down.
What happens when a lift is decelerating vertically upwards?
When a lift is decelerating vertically upwards, the occupants will experience a sensation of weight being greater than normal as the force of deceleration opposes the force of gravity. The lift will slow down as it reaches its destination floor, allowing for a smoother transition for passengers.
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!
How you calculate the kinetic energy of the particle projected vertically upwards?
The kinetic energy of a particle projected vertically upwards can be calculated using the formula: KE = 1/2 * m * v^2, where m is the mass of the particle and v is the velocity at which it is projected upwards. The kinetic energy is the energy associated with the motion of the particle.
How do you draw velocity time graph for a body thrown vertically upwards?
To draw a velocity-time graph for a body thrown vertically upwards, the initial velocity will be positive (upwards) and steadily decrease due to gravity until reaching zero at the peak. After the peak, the velocity becomes negative as the body falls back down. The graph will have a symmetrical shape with the velocity decreasing and then increasing back to the initial velocity.
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
When bullet is fired upwards vertically it gains in?
When a bullet is fired upwards vertically, it gains potential energy as it moves against gravity. This increase in potential energy comes at the expense of its initial kinetic energy. Eventually, the bullet will reach its maximum height and then begin to fall back towards the ground, converting its potential energy back into kinetic energy.
What causes the most earthquakes?
Earthquakes that causes most damage when two plates crashed and one plate moves upwards vertically than the other plate.
