T3.3 Newton's Laws of Motion Flashcard

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 speed and in a straight line 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).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What does it mean if an object is 'stationary'?

Back

It is not moving and remains in the same place.

Front

What is the formula to calculate force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What happens when a dog pulls on a leash according to Newton's Third Law of Motion?

Back

The leash pulls back on the dog with equal strength in the opposite direction.

Front

What is inertia?

Back

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

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the motion of an object.

Front

What is acceleration?

Back

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

Front

What is the relationship between mass and acceleration?

Back

As mass increases, for a given force, acceleration decreases.
