Front

What is displacement?

Back

Displacement is the final position minus the initial position, representing the shortest distance from the starting point to the endpoint in a specific direction.

Front

How do you construct a motion diagram?

Back

A motion diagram can be constructed by taking a series of photographs at equal time intervals of a moving object, perpendicular to the direction of motion, and overlaying the images to visualize position changes over time.

Front

What is the formula for average velocity?

Back

Average velocity is calculated as the total displacement divided by the total time taken.

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down or decelerating.

Front

If a car travels at a constant speed, what can be said about its acceleration?

Back

If a car travels at a constant speed, its acceleration is zero.

Front

What is the relationship between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

How do you calculate the displacement of an object given its initial and final velocities?

Back

Displacement can be calculated using the formula: Displacement = (Initial Velocity + Final Velocity) / 2 * Time.

Front

What is the significance of a motion diagram in physics?

Back

A motion diagram visually represents the position of an object at various time intervals, helping to analyze its motion.

Front

What is the effect of time on the distance traveled by an object moving at constant speed?

Back

The distance traveled by an object moving at constant speed is directly proportional to the time it has been moving.

Front

What does it mean for an object to have constant acceleration?

Back

Constant acceleration means that the object's velocity changes at a consistent rate over time.
