18 Questions
What type of motion is exhibited by a diagonal straight line on a velocity-time graph?
Constant acceleration
How can acceleration be defined?
Change in velocity per unit time
What does a constant slope on a velocity-time graph imply?
Constant acceleration
If a car travels 144 km/h, what is its speed in m/s?
80 m/s
Which quantity allows us to calculate acceleration using the formula: a = (v_f - v_i) / t?
Both initial and final speeds (v_f, v_i)
What happens to an object moving at a constant speed?
It maintains the same speed
If a car accelerates from 15 m/s to 21 m/s in 7 seconds, what is its average acceleration?
~0.86 m/s²
What does a diagonal straight line on a position-time graph indicate?
Constant speed
What does a diagonal straight line on a velocity-time graph indicate?
Constant acceleration
How is acceleration calculated when given initial and final velocities?
$\frac{v_f - v_i}{t}$
If a car accelerates from 20 m/s to 35 m/s in 5 seconds, what is its acceleration?
6 m/s²
What happens to an object moving with constant acceleration?
Its velocity changes by the same amount each second
In a position-time graph, a horizontal line indicates the object is:
At rest
If a car moves at a speed of 60 km/h, what is its speed in m/s?
20 m/s
A car decelerates from 30 m/s to 15 m/s in 4 seconds. What is its acceleration?
-4.5 m/s²
What does a horizontal line on a velocity-time graph signify?
Constant speed
How is acceleration defined?
$\frac{v_f - v_i}{t}$
What kind of motion does a diagonal straight line on a position-time graph represent?
Uniform motion
Learn about the definition of constant motion, where an object covers the same distance per unit time or changes its speed uniformly. Explore examples like a train moving between stations and a ball falling from a building to understand how constant motion occurs.
