A satellite moves around the earth in its orbit and does not escape from the space because the satellite
become weightless
move in a vacuum
always pulled by the earth gravitational force
moves with highest speed
Diagram shows a toy car tied with a string and fixed at one end on the floor. When it swings at the same length from the nail, the car moves in a circle.
Which of the following can explain the above situation?
There is a force acts in opposite direction with the car's weight
There is a force acts as centripetal.
There is a force acts in the direction of movement
There is a force acts away from the centrenof circle.
Diagram shows two object A and B with mass m1 and m2 respectively. The distance between center of the objects is r and the gravitational force is F.
F will decrease if
m1 increases
m2 increases
r increases
Diagram shows a girl whirling a pail horizontally.
What happen to the pail if the string suddenly breaks?
Spiral away from her hand
Fly directly away from the boy
Fly directly towards the boy
Fly off and follow the tangent to its circular path,
What happen to the weight of the object if the mass of Earth decreases one half from its original mass without changing its radius?
Does not change
Decreases to one half from original weight
Decreases to one quarter from original weight
increases double from original weight
