By now, we should all be comfortable with the fact that as long as there's
a force acting on an object, the object continues to accelerate, that is, to
move, in the direction of the force, with increasing speed.
Any two objects have a pair of equal forces acting on them ... the forces of
universal gravitation, which attracts every object to every other object. So
every two objects that are free to move must accelerate toward each other.
When I'm up in the air above the earth's surface, I'm attracted toward the earth
with a force of 185 pounds, and the earth is attracted toward me with a force of
185 pounds. Both I and the earth are accelerated by the forces on us.
My acceleration toward the earth ... the rate at which my speed increases ...
is 9.8 meters per second (32.2 feet per second) faster every second.
Since the earth's mass is somewhat greater than my mass but the force on it is
the same as the force on me, the earth accelerates toward me at a somewhat
lower rate.
What else can I help you with?
Why dont you do work when you carry an object at a constant velocity?
When you carry an object at a constant velocity, there is no net displacement in the direction of the force applied. Work is defined as force x distance x cos(theta), and since the displacement is zero in this case, the work done is also zero.
A change in a moving object's direction always results in a change in its?
velocity. When an object changes direction, its velocity vector changes, even if the object's speed remains constant. This change in velocity can be caused by forces such as gravity or friction acting on the object.
When a car rounds a corner going at constant speed is its acceleration is zero?
No, even if a car is moving at a constant speed while rounding a corner, it is still undergoing centripetal acceleration towards the center of the curve. This acceleration is responsible for changing the direction of the car's velocity.
What angle does his velocity make with the horizontal.?
The angle that the velocity makes with the horizontal is called the launch angle. It can be calculated using trigonometry by finding the arctangent of the vertical component of the velocity divided by the horizontal component.
How is the centripetal force on a rotating body affected if you double the radius and leave the tangential velocity the same?
If you double the radius while keeping the tangential velocity constant, the centripetal force will also double. This is because the centripetal force is directly proportional to the square of the velocity and inversely proportional to the radius. Therefore, doubling the radius increases the centripetal force required to keep the body rotating at the same speed.
Do most objects move at constant speed?
they do an if they dont then you die hard like mudkipz.ws/
What is something that does not change?
constant(s) are 1 or more objects that dont change...the control group all of them in one group
What is something that is not changing?
constant(s) are 1 or more objects that dont change...the control group all of them in one group

Is the value of g equals 9.8m s constant?
No. It is an approximation for objects near earth, objects further away from earth experience less force and therefore dont have as great an acceleration.
Why you draw the velocity triangles?
why dont you draw the velocity of triangles?
Why do you fear trees falling on you?
i dont.
How did Galieo apply the scientific methods to his study of falling objects?
i love him so much he was a legend and he helped create things that important to us that i dont know of but you might want to try google, that has some good infor good luck! He went to moon,he ate breakfast,he was science teacher,friends with lil wayne.
How do you get falling sand game started?
well, if you dont have java then the falling sand game wont start
Why dont astronauts hit there heads on the ceiling of the falling shuttle?
Astronauts inside a falling shuttle experience weightlessness because they are in a state of free fall alongside the shuttle. This means both the astronauts and the shuttle are falling together at the same rate, so there is no sensation of hitting the ceiling despite the lack of gravity.
When a car rounds a corner going at constant speed is its acceleration is zero?
No, even if a car is moving at a constant speed while rounding a corner, it is still undergoing centripetal acceleration towards the center of the curve. This acceleration is responsible for changing the direction of the car's velocity.
