Newton's Laws

Front

What is Newton's 1st Law of Motion?

Back

An object in motion stays in motion, and an object at rest stays at rest unless acted upon by an external force.

Front

What is Newton's 2nd 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).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is net force?

Back

The combination of all the forces acting on an object.

Front

What happens to a passenger in a car that stops suddenly?

Back

Due to inertia, the passenger will continue moving forward, pressing against the seatbelt.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

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 balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.
