What is the unit for speed?

m/s

Explain why a car turning a corner at a constant speed of 20 m/s is not traveling at a constant velocity.

Because the direction of the car is changing, velocity is not constant (vector).

Define distance.

Total length of an object's path.

Explain the motion of the object in the graph.

slow constant speed away from start, stopped, slow constant speed away from start, fast constant speed home

Calculate the speed of the object during the third section of movement

S=? D=30m T=3s S=D/T S=30m/3s S=10m/s

Explain why rate and speed are considered the same thing.

Both divide distance by time.

Define vector.

A quantity that includes both magnitude (size) and direction.

What does a horizontal line above the x axis represent on a speed vs time graph represent?

constant speed

What does negative slope represent on a speed vs time graph?

slowing down

What does a horizontal line on the x axis on a speed vs time graph represent?

motionless

Describe the acceleration of the object using each section of the graph

positive, zero, positive, negative

What is displacement?

An object's ending position compared to its starting point.

Describe the motion of the object using the graph.

accelerating quickly, constant speed, slow acceleration, slow deceleration

How do you calculate average speed?

total distance divided by total time

What does a diagonal, straight line represent on a distance vs time graph?

constant speed

Draw a graph for a person who walks up a hill at a constant speed, across the top, and down the other side.

See Graph on Board

When does an object's velocity change?

speed up, slow down, change direction

Define scalar.

A quantity that includes only magnitude (size).

How quickly an object is moving at a certain time is its...

instantaneous speed

How do you calculate distance?

Add up all of the lengths to get a total distance.

What is negative acceleration?

slowing down

What is positive acceleration?

speeding up

What does a curved line represent on a distance vs time graph?

non-constant speed (acceleration)

Explain the difference between speed and acceleration.

Speed only considers the distance and object moves in a given time, which acceleration includes how quickly the speed is changing in a given time with direction

Which term(s) is(are) scalar: distance, displacement, speed, rate, velocity, acceleration

distance, speed, rate

What does a horizontal line on a distance vs time graph represent?

motionless

What is the unit for acceleration?

m/s/s

What is the unit for rate?

m/s

How can you tell an object has moved?

The object's position changes compared to a reference frame.

What does a straight, diagonal line represent on a speed vs time graph?

constant acceleration

What does negative slope represent on a distance vs time graph?

going back to start

What is the unit for velocity?

m/s + direction

What does "delta v" represent?

change in velocity (final velocity minus initial velocity)

What is the unit for distance?

m (km)
