Motion, Forces, and Energy Comprehensive Assessment

Which of the following is a scalar quantity?

• Velocity
• Displacement
• Force
• Distance

What distinguishes a vector quantity from a scalar quantity?

• Size only
• Magnitude and direction
• Weight
• Temperature

A micrometer screw gauge is most useful for measuring:

• Ocean depths
• Room temperatures
• Very small distances
• Large building dimensions

Which tool helps calculate volume by displacement method?

• Micrometer
• Thermometer
• Measuring cylinder
• Stopwatch

Speed is calculated by:

• Distance × Time
• Distance ÷ Time
• Time ÷ Distance
• Distance + Time

On a displacement-time graph, a horizontal line indicates:

• Constant velocity
• Acceleration
• Object at rest
• Deceleration

Newton's Second Law states that:

• Objects always stay at rest
• Force equals mass times acceleration
• Gravity always pulls downward
• Energy cannot be created

Which is an example of a vector quantity?

• Mass
• Temperature
• Velocity
• Time

A velocity-time graph with a positive gradient represents:

• Constant speed
• Deceleration
• Acceleration
• Object at rest

Which force always acts downward towards Earth's center?

• Friction
• Tension
• Electrical force
• Gravitational force
