Forces and Motion

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is speed?

Back

The distance an object travels per unit of time, often measured in meters per second (m/s).

Front

What is the relationship between force and motion?

Back

An increase in force applied to an object typically results in an increase in its speed or change in motion.

Front

What is the engineering design process?

Back

A series of steps that engineers follow to come up with a solution to a problem, including identifying the problem, brainstorming, designing, testing, and improving.

Front

What does it mean for an object to be at rest?

Back

An object is at rest when it is not moving and its position does not change over time.

Front

What is acceleration?

Back

The rate at which an object changes its velocity, which can be an increase or decrease in speed.

Front

What is mass?

Back

The amount of matter in an object, usually measured in kilograms (kg).

Front

What is gravity?

Back

A force that pulls objects toward each other, such as the force that pulls objects toward the Earth.

Front

What is friction?

Back

A force that opposes the motion of an object, caused by the contact between two surfaces.
