They help us predict weather patterns.

They explain how physical systems operate, from planetary orbits to everyday machines.

They are only important for scientists.

They are unrelated to how the world works.

Objects remain at rest or in constant motion unless acted upon.

The rate of change in velocity is acceleration.

Speed with direction is called velocity.

Straight-line distance from start to end point is displacement.

Work is measured in joules.

Maximum work occurs when force aligns with displacement.

No work is done when force is perpendicular to motion.

Work is always positive.
