Newtons First Law (GCSE Physics)

A rocket in deep space, far from other bodies, travels at constant speed in a straight line. What does Newton’s First Law tell us about the forces on the rocket?

A block rests on an inclined plane with no motion. Which is the correct Newton’s First Law description of forces?

A bullet embedded in a stationary block causes the block to move. Which law explains why the block moves even though initially it was at rest?

A driver in a car suddenly brakes and a passenger lurches forward. Which explanation uses Newton’s First Law?

A cyclist stops pedalling but continues to roll along at constant speed. Why does the cyclist eventually slow to a stop even if no pedals are used?

Two identical boxes sit side by side. One is doubled in mass by filling with heavy material. If the same horizontal force is applied to both, what does Newton’s First Law (and Newton’s Second) predict?

A cup is on the dashboard of a moving car. The car turns left sharply and the cup seems to move right relative to the car. Which is the correct Newton’s First Law explanation?

A heavy suitcase on a stationary airport trolley will remain at rest unless a resultant force acts on it. Which statement best explains this using Newton’s First Law?

A spacecraft fires thrusters briefly then shuts them off. While thrusters are off the craft drifts at constant velocity. Which statement is correct?

A hockey puck is sliding; you observe no external horizontal forces. According to Newton’s First Law, which of the following is true?

A book slides on a table and stops because of friction. Which statement best describes the forces during the motion before stopping?
