Understanding Motion and Velocity Concepts

What is the first step in studying the motion of an object?

• Measuring its speed

• Observing its color

• Calculating its acceleration

• Defining a reference system

Which of the following is NOT a type of motion based on the shape of its trajectory?

• Static

• Random

• Circular

• Linear

How is speed defined in physics?

• Change in position per unit time

• Rate of change of velocity

• Total distance divided by total time

• Distance covered per unit time

Why is knowing only the speed of an object often insufficient?

• Because speed does not include direction

• Because speed is a scalar quantity

• Because speed is difficult to measure

• Because speed is always constant

What additional information does velocity provide compared to speed?

• Direction

• Distance

• Magnitude

• Time

How is velocity defined?

• Total distance divided by total time

• Change in position per unit time

• Distance covered per unit time

• Rate of change of speed

What is the main difference between displacement and trajectory?

• Trajectory is always a straight line

• Displacement considers the path taken

• Trajectory considers only the initial and final positions

• Displacement considers only the initial and final positions

How can motion be classified based on velocity?

• Accelerated and decelerated

• Constant and variable

• Uniform and non-uniform

• Linear and circular

What is a characteristic of uniformly accelerated motion?

• Constant speed

• Constant velocity

• Constant acceleration

• Variable direction

In uniformly accelerated motion, what happens to the distance covered in equal time intervals?

• It fluctuates

• It remains the same

• It decreases

• It increases
