Understanding Motion in a Straight Line

What type of motion is discussed in the video?

• Circular motion

• Random motion

• Motion in a straight line

• Rotational motion

What is a reference frame in the context of motion?

• A frame used to support objects in motion

• A scientific tool for measuring speed

• A set of axes used to describe the position and motion of an object

• A type of camera used to record motion

Which example illustrates the use of a moving reference frame?

• A car driving on a highway

• A bird flying in the sky

• A person moving in a boat

• A rocket moving towards space

What does the position of an object in linear motion depend on?

• The color of the object

• The weight of the object

• The reference frame used

• The speed of the object

What does displacement indicate in physics?

• The total path length traveled

• The speed of an object

• The time taken for a journey

• The shortest distance from the initial to the final position

What is the significance of the direction in the concept of displacement?

• It only affects the speed

• It is irrelevant to displacement

• It determines the vector nature of displacement

• It indicates the potential energy

How is average velocity calculated?

• Acceleration times time

• Speed multiplied by time

• Displacement divided by elapsed time

• Distance divided by time

What does negative average velocity indicate?

• The object is stationary

• The object is moving to the left

• The object is moving upwards

• The object is accelerating

What is the SI unit of acceleration?

• Meter per second

• Miles per hour per second

• Meter per second squared

• Kilometer per hour squared

Which statement is true about acceleration?

• It always follows the direction of motion

• It is a scalar quantity

• It can be opposite to the direction of motion

• It decreases as velocity increases
