4.04 Let the unbalanced force be with you AND 4.05 Motion Factors
4.07 Simple Machines
100
This can be measured by direction and position.
What is motion?
100
The less massive and object is the less of this is needed to move it.
What is force?
100
A force that that pulls objects to earth.
What is gravity?
100
An example of this force can be observed during a kickball game when the ball is pitched, but the force between the ball and the ground makes the ball stop before reaching the kicker.
What is friction?
100
A knife is an example of this kind of simple machine.
What is a wedge?
200
An objects position usually matches this.
What is its movement?
200
When an object's acceleration increases the force on the object also does this.
What is increases?
200
A form of energy that relies on weather conditions but does not use fuels formed from the decayed remains of plants or animals such as coal or oil (fossil fuels).
What is wind energy?
200
An example of this law can be observed when a tennis ball hits a net (an unbalanced force) and falls to the court.
What is Newton's first law?
200
A seesaw, a hammer, a crowbar, a light switch.
What is a lever?
300
The speed at which something moves in a particular direction.
What is velocity?
300
The force responsible for an object's change in motion and position.
What is an unbalanced force?
300
A simple machine that is usually used to hold things together,but Archimedes used a large one to lift water.
What is a screw?
300
When predicting the outcome of a race involving different sized cars down a ramp you must consider: mass, amount of force, distance, and this.
What is slope?
300
A screwdriver is this type of simple machine.
What is a wheel-and-axle?
400
To find this use the formula distance/time (d divided by t)
What is speed?
400
Equal forces acting in opposite directions on an object are balanced, resulting in this.
What is NO movement?
400
The simple machine most often used by a person in a wheel chair when entering a building that is not level with the ground.
What is an inclined plane?
400
An example of this law is the downward force of a rocket's boosters blasting the rocket up off the launch pad.
What is Newton's third law?
400
When raising a flag on a flagpole, you are using this type of simple machine?
What is a pulley?
500
A person using a stopwatch, measuring tape and a compass is most likely measuring this.
What is motion?
500
The two factors affecting the movement of an object, include the mass of the object and this.
What is size and direction of a force?
500
The type of potential energy an object has when it is elevated.
What is gravitational potential energy?
500
An example of this Newton's law can be observed when one race car accelerates off the starting line faster than another race car.
What is Newton's second law?
500
The six kinds of simple machines.
What are wedge, wheel & axle, screw, lever, inclined plane, and pulley?
