24-25 Science Semester 1 Exam

Front

What happens when forces are balanced on an object?

Back

The object will remain at rest or continue to move at a constant speed in a straight line.

Front

What happens when forces are unbalanced on an object?

Back

The object will accelerate in the direction of the net force.

Front

What is a positively charged object's interaction with a negatively charged object?

Back

The positive charge attracts the negative charge.

Front

What is a dependent variable in an experiment?

Back

It is the factor that is measured or observed in response to changes in the independent variable.

Front

What is static electricity?

Back

It is the buildup of electric charge on the surface of objects.

Front

How can increasing force affect the motion of an object?

Back

Increasing the force applied to an object can increase its acceleration and speed.

Front

What is the role of friction in motion?

Back

Friction opposes the motion of an object, slowing it down or preventing it from moving.

Front

What is the difference between an independent variable and a controlled variable?

Back

The independent variable is the factor that is changed in an experiment, while controlled variables are kept constant.

Front

What is the effect of gravity on objects?

Back

Gravity pulls objects toward the center of the Earth, affecting their weight and motion.

Front

What is the principle of attraction and repulsion in electric charges?

Back

Like charges repel each other, while opposite charges attract each other.
