1D Motion Test Review

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have only magnitude (e.g., speed, distance), while vector quantities have both magnitude and direction (e.g., velocity, displacement).

Front

Define displacement in the context of motion.

Back

Displacement is the vector quantity that represents the change in position of an object, measured as the shortest distance from the initial to the final position, along with the direction.

Front

What is the SI unit of speed?

Back

The SI unit of speed is meters per second (m/s).

Front

What is the formula for calculating acceleration?

Back

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravity only, with no other forces acting on it.

Front

What does a velocity-time (VT) graph represent?

Back

A velocity-time graph shows how the velocity of an object changes over time, with time on the x-axis and velocity on the y-axis.

Front

What does a constant slope on a VT graph indicate?

Back

A constant slope on a VT graph indicates constant acceleration.

Front

What is the significance of the area under a VT graph?

Back

The area under a velocity-time graph represents the displacement of the object during that time interval.

Front

What is the formula for calculating distance when given acceleration and time?

Back

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity that measures the total path length traveled, while displacement is a vector quantity that measures the shortest straight-line distance from the initial to the final position.
