Motion 1
The change in the position and distance away from the starting point of an object is known as this.
Displacement
What is a car doing if on a velocity-time graph both of its lines are in the same direction?
slowing down/speeding up
If Joe runs 4 miles in 1 hour and Bob runs 2 miles in 20 minutes, who is faster?
Bob is faster
True or False.
Acceleration can be negative and positve.
True
Motion of a car if the line on the distance-time graph is horizontal.
Not moving
A car slowing down has what kind of acceleration?
Negative acceleration
What is Nikki's total displacement if she drives 4 miles east from her house to pick up her friend Dave, and then drive 2 more miles east to school?
6 miles
Wha is the acceleration of a car traveling at 10 meters per second that takes 20 seconds to stop?
0.5 m/s2
The slope of a velocity vs. time represents this.
acceleration
The metric units for distance and displacement
meter
The amount an object moves is known as this.
Distance
The acceleration due to gravity is commonly represented using what variable?
g
A runner runs one lap around the track which is 400 meters the run at a speed of 6.67m/s.
How long did it take for them to run around the track
59.97sec.
A car moving at 50 km/hr slows down to a stop in 0.5 hours.
What is the cars acceleration?
-100km/hr2
What is the acceleration equation?
A= (Vf-Vi)/t
The rate at which an object's position changes with direction
Velocity
Have both magnitude (size) and direction
typically drawn as an arrow
vector
the motion of objects that fall due to gravity alone with no other forces acting upon them
Free Fall
Stan walks 10km west to the grocery store. He shops then walks back 10km east to his house. What distance did he cover?
20km
The slope of a distance vs. time graph represents this.
velocity
The distance traveled over time.
Speed
The units for acceleration can look like this
m/s2
What is the equation for speed?
S = d/t
What is Johnny's total displacement if he walks 2 miles to the school, and then takes the short cut back home that is only 1 mile?
zero
Units for Velocity and speed can look like what?
m/s
