1.
Which of the following factors does NOT affect the spring constant of a coil spring?
2.
Hooke's Law states that the extension of a spring is directly proportional to the applied force. What is the condition under which this law is valid?
3.
A block of weight 50 N is at rest on a smooth inclined plane at an angle of 40∘ to the horizontal. A frictional force, F R, prevents it from sliding down. What is the magnitude of this frictional force?
4.
A car is moving at a constant velocity of 20 m s−1. The engine provides a forward thrust of 1500 N. What is the magnitude of the total resistive force (air resistance and friction) acting on the car?
5.
What is the primary condition for an object to be in a state of equilibrium of forces?
6.
According to Newton's Second Law, if a non-zero resultant force acts on an object, what is the state of the objects motion?
8.
Two identical springs are arranged in parallel and a load is hung from them. How does the extension of this system compare to the extension of a single spring with the same load?
9.
The elastic potential energy stored in a spring is 0.4 J when it is extended by 5 cm. What is the force required to cause this extension?
10.
A free-body diagram for a book resting on a horizontal table would show which of the following forces acting on the book?
