Question

1. Plot the following graphs:

(a) distance –time graph for an object with uniform speed
(b) distance –time graph for an object with non- uniform speed
(c) velocity –time graph for uniform motion of a car
(d) Velocity –time graph for a car moving with uniform accelerations.
(e) Velocity –time graph for a car moving with non- uniform accelerations.
(f) A body at rest

Answer 1

(a) The distance-time graph for an object with uniform speed is giving by a straight line sloped graph with a constant positive or negative gradient as shown in the attached diagram

(b) The distance-time graph for an object with non-uniform speed is giving by a curved line sloped graph with varying gradient as shown in the attached diagram

(c) The velocity-time graph for a car with uniform motion is giving by a horizontal line graph at the speed of constant motion with a zero gradient as shown in the attached diagram

(d) The velocity-time graph for a car moving with uniform acceleration is giving by a straight line sloped graph with a constant positive or negative gradient as shown in the attached diagram

(e) The velocity-time graph for a car moving with non-uniform acceleration is giving by a curved line sloped graph with varying gradient as shown in the attached diagram

(f) According to Newton's first law of motion, an object at rest will remain at rest with no motion unless acted by a force, an therefore, will have no motion with time
