Newton's Laws of Motion Flashcard

Front

What type of force(s) will cause a change in an object's motion?

Back

Unbalanced forces cause a change in an object's motion.

Front

If a force of 26 N is exerted on two balls, a red one with a mass of 0.52 kg and a blue one with a mass of 0.78 kg, which ball will have the greater acceleration? (F=ma)

Back

The red ball will have the greatest acceleration.

Front

What law of motion states that an object at rest will stay at rest unless acted upon by an unbalanced force?

Back

Newton's 1st law of motion.

Front

If a person weighs 400N on Earth and stands on a scale balancing on one foot, what will the scale read?

Back

The scale will read the same (400N).

Front

Which of Newton's Laws explains why you can feel things that you touch?

Back

Newton's 3rd law.

Front

What is the formula for calculating force?

Back

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

Front

What is inertia?

Back

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

Front

What does Newton's 2nd law state about the relationship between force, mass, and acceleration?

Back

Newton's 2nd law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not cause a change in an object's motion.

Front

How does mass affect acceleration when a constant force is applied?

Back

Greater mass results in less acceleration when the same force is applied.
