When a block is oscillating, what is the position at which the velocity is maximised?

• Edges

• Equilibrium

• Half the total distance travelled

• At the beginning

Why do we make the approximation of small angles in a pendulum?

• Because the sine is not proportional to displacement.

• Because big angles doesn't generate motion.

• Because small angles are shorter.

• Because we can't observe big angles.

In Hooke's Law, what does constant k tell you?

• How stiff or loose a spring is

• How much force you require to bring back the spring to equilibrium

• How big or small a spring is

• How much will a spring stretch

What is an example of a restoring force?

• Hooke's law

• Normal force

• Friction

• Tension

In an oscillating block-spring system, where's the position at which the acceleration is zero?

• Edges

• Equilibrium

• There's no such position

• Depends on the arrangement of springs

In an oscillating block-spring system, where's the position at which the acceleration is maximum?

• Edges

• Equilibrium

• There's no such position

• Depends on the arrangement of springs

What is oscillatory motion?

• Repeated back and forth movement over the same path about an equilibrium position

• Repeated back and forth movement over the same path about any position

• Back and forth movement over the same path about an equilibrium position

• Repeated front movement over the same path about an equilibrium position

• Repeated back movement over the same path about an equilibrium position

What is restoring force?

• Force acting opposite to displacement to bring the system back to equilibrium, which is its rest position. The force magnitude depends only on displacement.

• Force acting perpendicular to displacement to bring the system back to equilibrium, which is its rest position. The force magnitude depends only on displacement.

• Force acting opposite to displacement to bring the system back to equilibrium, which is the edge. The force magnitude depends only on displacement.

• Force acting opposite to displacement to bring the system back to equilibrium, which is its rest position. The force magnitude depends only on the constant.

What does SHM stand for?

• Simple Harmonic Motion

• Simple Hinge Mechanism

• Sample Harmonic Mechanism

• Sample Hinge Mechanism

What is the amplitude of a wave?

• Maximum displacement of points on a wave

• Distance between two successive like points on a wave

• Distance between two points on a wave

• Maximum distance between two points on a wave
