If a satellite moves with a constant speed in a perfectly circular orbit around the Earth, what is the direction of the force of the satellite?
in the forward direction
the acceleration is zero because the speed in constant
inward toward the Earth
outward away from the Earth
An object moves in a circular path at a constant speed.
Compare the direction of the object's Force and acceleration vectors.
The vectors point in opposite directions
the acceleration is zero but the velocity is constant
both vectors point in the same direction
the vectors are perpendicular to each other
The Mood is accelerated towards Earth, so it is gradually getting closer to the Earth
True
False
You are making a circular turn in your car on a horizontal road when you hit a big patch of ice, causing the force of friction between the tires and the road to become zero. While the car is on the ice, it____.
moves along a path that is neither straight nor circular
moves along a straight-line path in its original direction
moves along a straight-line path toward the center of the circle
moves along a straight-line path in its original direction
A car goes around a circular curve on a horizontal road at a constant speed. What is the direction of the friction force on the car due to the road?
perpendicular to the curve inward
perpendicular to the curve outward
tangent to the curve in the forward direction
tangent to the curve opposite of the direction of the car's motion
As an astronaut approaches the Earth from Mars, what can be said about the force of gravity experienced between the Astronaut and the Earth only?

the force of gravity from earth is stronger as the astronaut is closer to mars
the force of gravity from earth is non-existent as the astronaut is closer to mars
the force of gravity from mars is weaker the further the astronaut is to mars
