Forces, Motion, Newton, Graphs

Front

What is force?

Back

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

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 unless acted upon by an unbalanced force.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Forces that are not equal and can cause an object to accelerate.

Front

What is the relationship between mass and force?

Back

According to Newton's Second Law, Force = Mass x Acceleration.

Front

What does a speed-time graph represent?

Back

It shows how speed changes over time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What does a horizontal line on a distance-time graph indicate?

Back

The object is at rest.
