Chapter 2 ~ Forces Q2 Review

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from moving when a force is applied.

Front

What is sliding friction?

Back

Sliding friction is the force that opposes the motion of two surfaces sliding past each other.

Front

What is rolling friction?

Back

Rolling friction is the force that opposes the motion of a rolling object, such as a wheel or ball.

Front

What is fluid friction?

Back

Fluid friction is the resistance encountered by an object moving through a fluid (liquid or gas).

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant velocity.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, causing the object to accelerate in the direction of the greater force.

Front

What surface allows a toy car to travel the furthest when pushed?

Back

A toy car travels the furthest on a smooth surface like ice due to reduced friction.

Front

How does friction affect motion?

Back

Friction opposes motion, slowing down or stopping moving objects.

Front

What is the role of friction in writing with a pencil?

Back

Friction between the pencil lead and paper allows the lead to leave marks on the paper.
