A bike travels 8 meters in 2 seconds, what is the speed of the bike?
40 m/s
4 m/s
16 m/s
.16 m/s
What force pulls the marble toward the bottom of the ramp?
electricity
friction
magnetism
gravity
How does Piper's ramp cause the car to increase speed?
Adding more height increases the potential energy, increases the kinetic energy, so the car rolls faster
Adding more height decreases the potential energy, which increases the energy, so the car rolls faster
Lowering the height decreases the potential energy, which decreases the kinetic energy, so the car rolls faster
Lowering the height increases the potential energy, which increases the kinetic energy, so the car rolls faster
Woody drove his race car. He slowed down and turned toward the pit lane. The most correct type of motion is
speed
velocity
acceleration
at rest
What is the speed of the car at 5 seconds?
1.4 m/sec
.14 m/sec
12 m/sec
3.5 m/sec
In the distance versus time graph such as the one pictured, a straight line means
the speed was increasing
the speed was decreasing
the speed was constant
the object was at rest
An electric skateboard travels north at 20 miles per hour. The most correct type of motion is
speed
acceleration
at rest
velocity
Students begin measuring the speed of a ball rolling down a ramp. What is the speed of the ball at .4 seconds?
.25 cm/sec
2.5 cm/sec
25 cm/sec
40 cm/sec
In a distance versus time graph, an upward curve in the line means
constant speed
velocity
acceleration
at rest
Predict what will happen if the pairs pull with force shown in the picture?
Balance forces will not allow the flag to move
The pair pulling with 12N of force will move the flag to their side
The pair pulling with 10N of force will move the flag to their side
The forces will cancel each other out the flag will not move
The best example of a balanced forces is
A ball just kicked along a flat surface
A roller coaster slowing down on an incline
A bus staying parked in a garage
A roller coaster slowing down on an incline
An object in motion will stay in motion unless acted on by
a balanced force
an unbalanced force
potential energy
kinetic energy
Which of the inclined planes should be used for the greatest mechanical advantage?
A
B
What will slow the box as it slides to the bottom of the ramp?
gravity
friction
inertia
magnetism
The BMX ramp is 30 meters high with a length of 10 meters. The rider travels with a force of 40 Newtons. Calculate the work.
300 Newton meters
400
400 Newton meters
300
How does the length of the ramp change the force needed?
The taller the ramp, the less work you need to move something up the ramp
As the length of the ramp increases, the amount of the force needed decreases
As the length of the of the ramp increases, the amount of the work done decreases
The amount of force needed to move an object never changes but the amount of work does change
How can you lower the force needed to move an object up an inclined plane?
Lower the force by making ramp longer
Lower the force by making ramp shorter
Increase the force by making the ramp longer
Increase the force by making the ramp shorter
