Study Notes
Graph Analysis
- Slope of +4 is present in graph (D)
- Positive slope is present in graphs (A) and (C)
- Velocity-displacement graph of a particle moving along a straight line is shown in figure, and the velocity as a function of x (0 ≤ x ≤ 1) is represented by options B, C, or D
Quadratic Equations
- If y = x² + 2x - 3, then the y - x graph is represented by option B
- Graph of x²y = 2 is best represented by option (C)
Spring Force and Potential Energy
- Spring force is given by F = -kx, where k is a constant and x is the deformation of the spring
- F - x graph is represented by option (C)
- Potential energy of a spring is U = 5x², where x is in meters and U is in joules, when the spring is elongated by x metres
Velocity and Time
- Velocity v varies with time t as v = t², so the plot between v and t will be parabolic, represented by option (A)
- Velocity can first increase and then decrease, first decrease and then increase, decrease continuously, or increase continuously
