Dynamics #1

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 with the same speed and in the same direction unless acted upon by a net external force.

Front

What does it mean for an object to move with constant velocity?

Back

It means the object is moving at a steady speed in a straight line without any change in direction.

Front

What is the relationship between force and motion according to Newton's Second Law?

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 happens to an object when no net force is acting on it?

Back

It will continue to move with constant velocity.

Front

What is inertia?

Back

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

Front

How does an increase in speed affect the motion of a car?

Back

If a car increases its speed, the forward velocity increases, which can cause objects inside the car to move forward relative to the car.

Front

What is the significance of the phrase 'Buckle up - it's the State Law'?

Back

It emphasizes the importance of seatbelts in preventing injury during sudden stops or collisions, illustrating Newton's First Law.

Front

What is a net force?

Back

A net force is the overall force acting on an object when all the individual forces are combined.

Front

What is the effect of a net force on a moving object?

Back

A net force will cause the object to accelerate, changing its velocity.

Front

What does it mean for a force to be perpendicular to velocity?

Back

A force that is perpendicular to the velocity of an object will change the direction of the object without changing its speed.
