Forces and Motion Review

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction.

Front

If an object has equal positive and negative charges, what is its electrical charge?

Back

Neutral or no charge.

Front

What two components make up velocity?

Back

Speed and direction.

Front

What happens when two like charges come near each other?

Back

They repel each other.

Front

What happens when two opposite charges come near each other?

Back

They attract each other.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the effect of gravity on objects?

Back

Gravity pulls objects toward the center of the Earth, giving them weight.
