Lesson 2: Force and Acceleration

Front

What is force?

Back

A push or pull acting on an object.

Front

What is acceleration?

Back

The rate at which an object's velocity changes over time.

Front

What is net force?

Back

The total force acting on an object when all the individual forces are combined.

Front

What does a position vs. time graph show?

Back

It shows how an object's position changes over time.

Front

What does it mean if an object is accelerating?

Back

It means the object's speed is changing, either increasing or decreasing.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What happens to an object at rest when a net force acts on it?

Back

It will start to move in the direction of the net force.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F = ma).

Front

What does it mean if a car is changing direction but moving at a constant speed?

Back

The car is accelerating because acceleration includes changes in direction.

Front

What is a balanced force?

Back

When two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.
