Physics - Chapter 1 Test Review

Front

What is a Scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude and no direction. Examples include speed, mass, and temperature.

Front

What is a Vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction. Examples include velocity, displacement, and force.

Front

What is Displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction. It is a vector quantity.

Front

What is Speed?

Back

Speed is the distance traveled per unit of time, regardless of direction. It is a scalar quantity.

Front

What is Velocity?

Back

Velocity is the rate at which an object changes its position, defined as displacement per unit of time. It is a vector quantity.

Front

What is Acceleration?

Back

Acceleration is the rate of change of velocity per unit of time. It can be positive (speeding up) or negative (slowing down) and is a vector quantity.

Front

What is a Motion Diagram?

Back

A motion diagram is a visual representation of an object's position at various times, showing how the object moves over time.

Front

What does it mean for images in a motion diagram to be taken at equal intervals of time?

Back

It means that the images represent the object's position at consistent time intervals, allowing for accurate analysis of motion.

Front

How do you calculate Displacement?

Back

Displacement can be calculated by subtracting the initial position from the final position, taking direction into account.

Front

What is the difference between Distance and Displacement?

Back

Distance is the total path length traveled, while displacement is the straight-line distance from the starting point to the endpoint, including direction.
