Science Final Review

How can you make an electromagnet stronger?

• You can add more coils or add an iron core.

• You can add another battery.

• You can make all of the coils wider and larger.

• It is impossible.

What is Newton's first law of motion?

• Speeding up, slowing down, and changing direction is all acceleration.

• An object will stay in motion or at rest until another force acts upon it.

• Energy cannot be destroyed in chemical reactions.

What is the strongest part of a magnet?

• The bottom of the magnet.

• All parts of the magnet are equally strong.

• The magnetic poles.

• The top of the magnet.

What will like and opposite poles of magnets do when they are put together?

• They will not react unless at least 5 magnets are present.

• Like poles will repel each other, while opposite poles will attract.

• Both like and opposite poles will attract each other.

• Like poles will attract, while opposite poles repel each other.

What type of circuit is this image demonstrating?

• Parallel circuit.

• Series circuit.

• Whole circuit.

What is the definition of mass?

• The force pulling an object based on gravity.

• The amount of matter in an object.

• The weight of an object, but with height.

If one of three light bulbs burned out in a series or parallel circuit, which would continue to work and why?

• The parallel circuit would continue to work because it has multiple paths, meaning another path would continue to flow and power other light bulbs.

• Neither because they would not be complete and the electricity would not flow through burned out light bulbs.

• The parallel circuit because it only has one path meaning the electricity would continue to power and push through.

• The series circuit because it has multiple paths, meaning another path would continue to flow and power other light bulbs.

What is the definition of motion?

• The change in height of an object in relation to weight.

• The change in position or orientation of a body with time.

• When a object moves.

What is the equation for speed?

• m/s

• Speed=distance/time

• Speed=time/distance
