Force and Motion Review

Front

What is force?

Back

A push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is acceleration?

Back

The rate of change of velocity of an object, which can be an increase or decrease in speed.

Front

What is balanced force?

Back

Forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What is unbalanced force?

Back

Forces that are not equal, causing a change in the motion of an object.

Front

What is speed?

Back

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

Front

What is constant speed?

Back

When an object covers equal distances in equal intervals of time.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, an object with a smaller mass will accelerate more than an object with a larger mass when the same force is applied.

Front

What is Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is Newton's second law of motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).
