A roller coaster car starts at rest at the top of a hill. Ignoring friction, as it goes down the hill, its:
Potential energy increases and kinetic energy decreases.
Potential energy decreases and kinetic energy increases.
Both potential and kinetic energy increase.
Both potential and kinetic energy decrease.
In the absence of air resistance, a freely falling object:

Gains kinetic energy equal to the loss in potential energy.
Loses both kinetic and potential energy.
Gains both kinetic and potential energy.
A ball is thrown vertically upwards. Neglecting air resistance, which of the following remains constant throughout its motion?
Kinetic Energy
Potential Energy
Velocity
Total Mechanical Energy
Two satellite A and B, ratio of masses are in circular orbits of radii and . Then ratio of total mechanical energy of A to B is
A missile is launched with a velocity less than the escape velocity. The sum of its kinetic and potential energy is
positive
negative
zero
May be positive or negative depending upon its initial velocity
Two identical satellites are at and away from earth surface, the wrong statement is
Kinetic energy of the nearer satellite is more
Total energy of the nearer satellite is more negative
Potential energy of the nearer satellite is more negative
Angular momentum of the nearer satellite is more
A satellite S is moving in an elliptical orbit around the earth. The mass of the satellite is very small compared to
The mass of the earth. Then,
The speed of the satellite is constant.
The speed of the satellite is maximum when it is nearest to the earth.
The speed of the satellite is maximum when it is farthest from the earth.
The speed of the satellite increases continuously.
