Force and Motion Flashcard

Front

What is the net force acting on an object at rest?

Back

The net force is zero.

Front

What is the difference between speed and velocity?

Back

Speed is scalar, while velocity is vector.

Front

What are the three types of motion?

Back

Linear motion, circular motion, and oscillatory motion.

Front

What is Newton's first law of motion?

Back

An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and direction, unless acted upon by an external force.

Front

What is the direction of force when an object is pushed to the right?

Back

The direction of force is to the right.

Front

What is force?

Back

A push or pull acting on an object.

Front

What is mass?

Back

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

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is friction?

Back

A force that opposes the motion of an object.
