Unit 2: Force s & Motion Post Review

Front

What is force?

Back

A push or pull on an object that can cause it to change its velocity (speed or direction).

Front

What is motion?

Back

The change in position of an object over time.

Front

What is mass?

Back

The amount of matter in an object, typically measured in kilograms.

Front

What is acceleration?

Back

The rate at which an object changes its velocity, which can be a change in speed or direction.

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 for an object to change speed?

Back

It means that the object's velocity is increasing or decreasing over time.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is a net force?

Back

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

Front

What happens when two objects collide?

Back

They exert forces on each other, which can change their speeds and directions.
