Name the three ways that an object can "Accelerate".
Speeding Up
Slowing Down
Changing Direction
100
What measurement matches each of these labels?
m/s2
N
kg
m/s east
m
m/s2 - acceleration
N - Force
kg - mass
m/s east - velocity
m - distance
100
Which of Newton's Laws states that the net force on an object is equal to the product of its mass times its acceleration?
Newtons Second Law
100
What happens to the motion of an object that is acted upon by balanced forces?
It has not change in motion: If it is resting, it will continue to rest. If it is moving, it will continue to move at the same speed and in the same direction.

Label each of these graphs:
Left: Accelerating (speeding up)
Right: Decelerating (slowing down)
100
Is this an example of acceleration: A Ferris Wheel spins at a slow steady rate
Yes, changing direction
100
What force is needed to throw a .5 kg ball upward at a rate of 10m/sec2?
5 Newtons
100
Which of Newton's Laws states that for every action there is an equal and opposite reaction?
Newton's Third Law
100
If a book rests on a table, what forces are acting on it?
Gravity is pulling down, the table is pushing up.
100
If you threw a ball from the Artemis II into space where there is no gravity and no friction, what would happen to the motion of the ball?
It would travel in a straight line and a steady speed forever - same speed, same direction.
100
Is this an example of acceleration: A car turned right into the parking lot
Yes, changing direction
100
An object is traveling at 8 m/s. It accelerates to 12 m/s in 2 seconds. What is the acceleration of the object?
2 m/s2
100
Which law is also referred to as the Law of Inertia?
Newton's First Law
100
In a tug-of-war, the blue team pulls to the left with a force of 300N and the red team pulls to the right with a force of 200N. What is the net force?
100N left
100
What is the difference between braking distance and reaction time?
Reaction time - the time it takes the driver to apply the brakes
Braking distance - the distance it takes the brakes to stop the car
100
Is this an example of acceleration: a jogger runs at a steady 6mph
No, constant speed
100
What is the formula used to calculate the acceleration of an obect?
A = Final Velocity - Initial Velocity
Time
100
Which of Newton's Laws states that an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an unbalanced force?
Newton's First Law
100
How do you find the net force of two forces that are acting in the opposite direction?
Subtract
100
What vocabulary term matches this definition: "A force that exists between two objects that are in contact and opposes the motion of the objects"?
Friction
100
Is this an example of acceleration: a worm crawls slowly across the sidewalk.
No, constant speed
100
What is the formula used to calculate the force on an object?
Force = mass x acceleration
100
If Newton's First Law states that an object in motion will remain in motion forever, why does a ball rolling along the floor eventually stop moving?
Friction causes the balls motion to stop.
100
How do you find the net force of two forces that are acting in the same direction?
Add
100
What vocabulary term matches this definition "the distance a vehicle travels from the moment the driver applies the brakes until the vehicle comes to a complete stop"?
Braking Distance
