What is motion defined as in physics?
What is the SI unit of acceleration?
Instantaneous velocity is defined as:
In the equation v = v₀ + at, what does 'a' represent?
Sample Questions
Which graph represents motion with zero acceleration?
Show answer
A straight line parallel to the time axis on a velocity-time graph
For uniform motion, acceleration is zero and the velocity remains constant. In a velocity-time graph, a constant velocity is shown by a straight line parallel to the time axis. This is the graph that represents zero acceleration.
What does the area under a velocity-time graph represent?
Show answer
Displacement
The area under a velocity-time curve represents the total displacement of an object during that time interval.
What is the difference between speed and velocity?
Show answer
Velocity includes direction, speed does not
Velocity is a vector quantity that includes both magnitude and direction, while speed is a scalar quantity representing only magnitude.
Which kinematic equation relates velocity, acceleration, and displacement?
Show answer
v² = v₀² + 2ax
This equation relates final velocity, initial velocity, acceleration, and displacement without explicitly involving time.
