1.1Which of the following is a contact force?
Tick ( ) one box.
[1 mark]
Electrostatic force
Gravitational force
Magnetic force
Air resistance
A student pulls down diagonally on a spring that is attached to a
1.2
clamp stand. The spring is stretched with a force of 25 N applied at an angle
of 37° below the horizontal, as shown in the diagram.
Resolve the 30 N force to find its horizontal component
[2 marks]
Horizontal component = 30 × cos(37°)
Horizontal component = 30 × 0.798 = 23.94 N ≈ 24 N
24 N
1.3
The spring has been deformed elastically.
Explain what meant by elastic deformation.
[2 marks] will return to its original shape/length – 1 mark when the force
is removed – 1 mark
1.4 The spring was stretched a distance of 30cm. The spring has a spring constant
of 150 N/m.
, 3
Calculate the elastic potential energy stored in the spring. [3 marks]
Elastic potential energy = 1/2 × spring constant × extension2
Elastic potential energy = 1/2 × 150 × 0.302
Elastic potential energy = 6.75 J
Elastic potential energy = 6.75 J
The student is tasked with investigating how the force applied to the spring
1.5
affects its extension.
[6 marks]
Describe how the student should carry out this investigation.
You may include a diagram.
set up a clamp stand with a clamp hang the
spring from the clamp Use clamp to fix
apparatus to the bench
use a second clamp and boss to fix a (half)
metre rule alongside the spring
record the ruler reading that is level with the
bottom of the spring
hang a 1 N / a known weight from the bottom
of the spring
record the new position of the bottom of the
spring calculate the extension of the spring
add further weights to the spring and repeat
measurements.
2.1 Transverse and longitudinal waves are the two types of waves.
State the difference between a transverse and longitudinal wave.
[2 marks]
Transverse waves oscillate perpendicular to the direction of energy transfer - 1
