Newton's Laws

According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will

• remain in motion.
• eventually come to a stop.
• change its momentum.
• accelerate.

A sled sliding on a flat, icy surface with a constant velocity is best described by

• Newton’s first law of motion for objects at rest.
• Newton’s first law of motion for objects in motion.
• Newton’s second law of motion.
• Newton’s third law of motion.

Acceleration is caused by a force acting on a mass.

• Newton’s first law of motion
• Newton’s second law of motion
• Newton’s third law of motion

Forces always act in equal and opposite pairs.

• Newton's 1st Law
• Newton's 3rd Law
• Newton's second law
