What energy transformations take place when you ride a skateboard?
Gravitational / chemical energy from your leg, to kinetic energy when you push the board along which then transfers to heat and sound as you go along.
What is the change when an object is pushed along an inclined plane to a height?
The object's height and gravitational potential energy both increase.
What is the direction that gravity pulls?
The gravitational force between two masses acts along the line that joins their centers of mass.
What forces are balanced when something floats?
upthrust keeps the object floating the gravitational pull keeps it along the meniscus of the averaged water
What affects the time that a horizontally projected object remains in the air?
When I see the words "the following", I can't help it ... I always suspect thatthere's a list of acceptable choices that goes along with this question but you'renot letting me see them for some reason.If you'll ignore the effect of air resistance, then the time a horizontally projected objectremains in the air is the time it would take to hit the ground if it were simply dropped.That's sqrt( 2 x height/gravitational acceleration)seconds
Is the moon following us?
The moon is stuck in our gravitational pull, it doesn't exactly follow. Just "tags along"
What a force is in physics?
Force is defined to be the one which changes or just tries to change either the state of rest of a body or its uniform motion along a straight path. Weight is the force exerted by the gravitational pull on the body. If m is the mass of the body then its weight will become mg, where g is the acceleration due to gravity.
What affects the shape of the planet's orbit?
The size of the planet along with the gravitational force within the planet.
What affects the shape of a planets orbit?
The size of the planet along with the gravitational force within the planet.
As the speed of a bicycle moving along a horizontal surface increases from 2 meters per second to 4 meters per second the bicycle's gravitational potential energy?
There is no change. The bike is moving along a horizontal surface, and only a change in height can change the gravitational PE.
What energy transformations take place when you ride a skateboard?
Gravitational / chemical energy from your leg, to kinetic energy when you push the board along which then transfers to heat and sound as you go along.
If a person exerted an effort force of 250 newtons to roll the barrel along the ramp what is the efficiency of the ram?
You would need to know the length and height of the ramp.
What is the change when an object is pushed along an inclined plane to a height?
The object's height and gravitational potential energy both increase.
What is the direction that gravity pulls?
The gravitational force between two masses acts along the line that joins their centers of mass.
Why does the revolution of the moon along with the Moon's gravity create spring tides?
The Earth's gravitational attraction to the Moon causes spring tides. The area of Earth closest to the moon will experience the gravitational pull of the moon. The oceans react to this gravitational pull by creating a bulge on the side of Earth that faces the moon.
What forces are balanced when something floats?
upthrust keeps the object floating the gravitational pull keeps it along the meniscus of the averaged water
What is postherpetic neuralagia?
Pain along the nerves following herpes
