Is displacement a scalar or a vector quantity?

What is a VECTOR?

100

This formula is used to find average velocity.

What is Vavg=

(Deltax)/(Deltat)

100

An object travels 20 meters in 4 seconds. What is its average velocity?

What is 5 m/s?

100

This describes an object's location compared to a chosen reference point.  

What is position?

100

This is the SI base unit for length.

What is the meter (m)?

200

Is speed a scalar or a vector quantity?

What is a scalar?

200

This formula is used to find average acceleration.

What is aavg=

(Deltav)/(Deltat)

200

A runner's velocity changes from 4 m/s to 10 m/s in 3 seconds. What is the runner's average acceleration?

What is 2 m/s²?

200

This is the total length of the path an object travels, regardless of direction.

What is distance?

200

This is the SI base unit for time.

What is the second (s)?

300

Is acceleration a scalar or a vector, and what does its direction tell you?

What is a vector; its direction tells you the direction of the change in velocity?

300

This formula finds displacement when you know the final and initial positions.

What is xf-xi =

Deltax

300

An object starts at 5 meters and ends at 25 meters. What is its displacement?

What is 20 meters?

300

This describes how quickly an object's position changes with time.

What is velocity?

300

These are the digits in a measurement that are known with certainty plus one estimated digit.

What are significant figures?

400

Is distance a scalar or a vector quantity, and how does it differ from displacement?

What is a scalar; distance measures total path traveled, while displacement includes direction?

400

This formula finds distance between any two points

What is 

sqrt(x^2+y^2

400

A car travels 60 meters in 5 seconds. What is its average velocity?

What is 12 m/s?

400

This describes how quickly an object's velocity changes with time.

What is acceleration?

400

When multiplying or dividing measurements, the final answer should have this many significant figures.

What is the same number of significant figures as the measurement with the fewest?

500

Is momentum a scalar or a vector quantity, and what determines its direction? 

Hint: momentum=mass*velocity

What is a vector; its direction is the same as the object's velocity?

500

This formula gives the instantaneous velocity, or velocity at a specific moment, using position and time.

What is

v=\frac{dx}{dt}

?

500

A car has an initial velocity of 10 m/s, accelerates at 2 m/s² for 5 seconds, and continues in the same direction. What is its final velocity?

What is 20 m/s?

500

This is the velocity or acceleration of an object at one specific moment in time, rather than over a time interval.

What is instantaneous velocity or instantaneous acceleration?

500

When adding or subtracting measurements, the final answer is rounded based on this place value.

What is the least precise decimal place?

600

An object's velocity is zero at a particular instant. Does that necessarily mean its acceleration is also zero?

What is no, an object can have zero instantaneous velocity while still having acceleration?

600

An object's initial velocity is 5 m/s and its acceleration is 3 m/s². After 4 seconds, what is its final velocity?

What is 17 m/s?

600

An object travels in a circle at a constant speed. Is its velocity constant?

What is no, because its velocity is changing direction?

600

This is the rotational equivalent of linear velocity and describes how quickly an object’s angular position changes with respect to time.

What is angular velocity?
