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 distance-time graph, it is an angle straight line like a steep slope?
constant speed
DAILY DOUBLE
A jogger goes from being stationary to 9m/s in 6 seconds. What is the runners acceleration?
True or False.
Acceleration can be negative and positve.
True
What are is the name for a group of crows?
A murder
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 total amount an object moves is known as this.
Distance
What is Newton's 1st Law of Motion?
An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
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.
What is Newton's 2nd Law of Motion?
Expressed as F = ma, states that the force (F) acting on an object is equal to its mass (m) multiplied by its acceleration (a), meaning a larger force is needed to accelerate a heavier object.
DAILY DOUBLE
What is the speed of a wagon that travels 80 meters in 5 seconds?
The rate at which an object's position changes with direction. (Speed and Direction)
Velocity
What is one example of a constant acceleration?
Free fall, plane taking off, ice skater, etc.
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
What is Newton's 3rd Law of Motion?
For every action there is an equal and opposite reaction
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 takes 1 mile?
1 mile
Motion of a car if the line on the distance-time graph is horizontal.
Not moving
