100
On a position-vs-time graph, the slope represents this.
What is velocity?
100
The following motion map represents this type of motion:
What is constant velocity?
100
When an object is not accelerating, the forces on the object are in this state.
What is balanced?
100
This is required in order for an object to accelerate.
What is a force?
100
These are the two models we have for the motion of objects.
What are constant velocity and uniform acceleration?
200
On a velocity-vs-time graph, the slope represent this.
What is acceleration?
200
On a motion map, the dot represents this.
What is the position of the object.
200
These two fundamental factors are the only things that affect the acceleration of objects.
What are force and mass?
200
It's the acceleration of an object that starts at 50 m/s and slows down to 20 m/s over 6.0 seconds.
What is 5.0 m/s/s?
200
These are the two models we have for forces on an object.
What are the balanced force model and the constant force model.
300
On a velocity-vs-time graph, the area underneath the curve or line represents this.
What is displacement?
300
On a motion map, the arrows extending from each dot represent this.
What is the velocity?
300
A train crashes into a car stalled on the tracks (luckily no one was hurt). Which object exerted a greater force on the other: the train or the car?
What is neither - they exerted the same force.
300
When objects are in free-fall in the horizontal direction, objects will experience this acceleration.
What is ZERO (0)?
300
Joe has a mass of 60 kg. What would be the force of gravity on Joe?
What is about 600 N?
400
When the position-time graph is linear, the object is moving this way.
What is constant velocity?
400
When the arrows extending from each successive dot are getting smaller, the object is doing this.
What is slowing down or accelerating (negatively)?
400
A 1000 kg car travels down a straight road at constant speed of 20 m/s. The net force on the car is this.
What is ZERO (0).
400
Neglecting friction or air resistance, objects near the surface of the earth will fall with this acceleration.
What is -9.8 m/s/s?
400
Joe has a mass of 60 kg. What would be his acceleration were he to fall off a building?
What is -9.8 m/s/s?
500
When the velocity-time graph is linear with a slope not equal to zero, the object is moving this way.
What is accelerating or uniform acceleration?
500
In this type of motion, arrows in the horizontal and vertical direction are shown separately.
What is projectile or free-fall motion, when objects are flying through the air.
500
An elevator accelerates a 100-kg person from rest to 2 m/s. During this time, which exerts a greater force on the other: the elevator or the person?
What is neither - they exert equal and opposite forces on each other.
500
TRUE or FALSE and explain: A car travels at a constant speed of 50 miles per hour, so it cannot be accelerating.
What is FALSE - it can change DIRECTION, which would change the VELOCITY, which would require an acceleration.
500
Joe has a mass of 60 kg. His shoes provide a coefficient of friction static friction of 0.5. What is the maximum force that can be applied before he will slide?
What is 300 N?
