Unit 3 Review

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F=ma).

Front

What does the term 'reaction' mean in Newton's Third Law of Motion?

Back

In Newton's Third Law, 'reaction' refers to the equal and opposite force that occurs in response to an action force.

Front

What does a dot diagram represent in motion analysis?

Back

A dot diagram visually represents the position of an object at equal time intervals, helping to analyze its motion.

Front

What does it mean when an object is 'speeding up'?

Back

'Speeding up' means that the object's velocity is increasing over time.

Front

What does 'decreasing velocity' indicate on a graph?

Back

A graph showing decreasing velocity indicates that the object is slowing down over time.

Front

What is the definition of 'constant velocity'?

Back

Constant velocity means that an object is moving at a steady speed in a straight line without changing its direction.

Front

What is an example of balanced forces?

Back

An example of balanced forces is a tug of war where both sides pull equally, resulting in no movement.

Front

What is the significance of mass in Newton's Second Law?

Back

Mass is a measure of the amount of matter in an object and affects how much force is needed to accelerate that object.

Front

What is the relationship between force, mass, and acceleration?

Back

The relationship is described by the formula F=ma, meaning that force equals mass times acceleration.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to a reference point over time.
