6.5.4.1.3 AQA Velocity and Motion

What is the velocity of an object?

• Its speed in a given direction

• Its speed without direction

• Its acceleration in a given direction

• Its mass in a given direction

Velocity is considered a:

• Scalar quantity

• Vector quantity

• Mass quantity

• Time quantity

What should students be able to explain regarding vector and scalar quantities?

• The difference as it applies to displacement, distance, velocity, and speed

• The difference as it applies to mass and weight

• The difference as it applies to time and space

• The difference as it applies to energy and power

In circular motion, what remains constant?

• Velocity

• Speed

• Direction

• Acceleration

In circular motion, what changes?

• Speed

• Mass

• Velocity

• Time

Which of the following is a vector quantity?

• Distance

• Speed

• Velocity

• Time

What is required to fully describe a vector quantity?

• Only magnitude

• Only direction

• Magnitude and direction

• Only speed

Which of the following is NOT a vector quantity?

• Displacement

• Velocity

• Speed

• Force

What is the main difference between speed and velocity?

• Speed includes direction, velocity does not

• Velocity includes direction, speed does not

• Speed is a vector, velocity is a scalar

• Speed is always greater than velocity

What type of motion involves constant speed but changing velocity?

• Linear motion

• Circular motion

• Oscillatory motion

• Random motion
