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 are the forces acting on a football?
-- the gravitational attraction between the football and the Earth, acting vertically downward; -- the normal force of the ground or the shelf under the football, acting vertically upward. These two forces are precisely equal and opposite. If they're weren't, then the football would be accelerating vertically, not at rest.
A cricket ball is projected vertically upward what kind of acceleration is acting on the ball?
When a cricket ball is projected vertically upward, the acceleration acting on the ball is gravitational acceleration directed downward. This causes the ball to slow down until it reaches the highest point of its trajectory, then it accelerates back downward due to gravity.
When you move upward in the atmosphere what happens to the temperature?
When you move upward in the atmosphere the temperature get lowered.
What is the magetic south pole?
Because the Earth wobbles on its path through the universe, the magnetic South Pole indicates the place on the planet where the geo-magnetic field lines are directed vertically upward.
How is possible for air pressure to exert a vertically upward force on a ceiling?
Air pressure exerts a vertically upward force on a ceiling due to the weight of the air above pushing down on the air below. This pressure difference results in a net force that pushes upward on the ceiling, according to Newton's third law of motion.
What is the acceleration of an object moving upward?
On earth, the vertical acceleration of any object that's free to move vertically,and has no artificial force imposed on it, is 9.8 meters (32.2 feet) per second2,directed downward. The source of the acceleration is the mutual gravitationalattraction between the object and the earth.
What are the forces acting on a football resting?
-- the gravitational attraction between the football and the Earth, acting vertically downward; -- the normal force of the ground or the shelf under the football, acting vertically upward. These two forces are precisely equal and opposite. If they're weren't, then the football would be accelerating vertically, not at rest.
Which way do winds in high pressure systems move both horizontally and vertically?
A thermohaline current flows vertically as it is driven by gravity. In fluid dynamics, we call this kind of current a gravity current.
What are the force that exerted to a hanging pen?
The forces acting on a hanging pen are gravitational force pulling it downward and tension force in the string supporting it. The gravitational force acts vertically downward on the pen due to Earth's gravity, while the tension force in the string acts vertically upward to counterbalance the weight of the pen.
A rocket of initial mass m0 is shot vertically upward Assume that the motion occurs under constant gravitational acceleration g Let the initial velocity of the rocket on the surface of the earth be?
the initial velocity of the rocket is zero.
When warm air move upward energy is move by?
Temperature
