Newton's Laws of Motion

Front

What is Newton's 2nd law of motion?

Back

Force = Mass multiplied by acceleration.

Front

Which one needs a greater net force to move, a kilogram of feathers or a kilogram of iron?

Back

They need the same net force.

Front

What is the net force if there are 4000 N acting to the left?

Back

4000 N left.

Front

What are examples of unbalanced forces?

Back

A car speeding up, a dog slowing down, and a person turning around the block.

Front

If you double the mass of an object with the same force applied to it, what happens to the acceleration?

Back

The acceleration will cut in half.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration.

Front

What is inertia?

Back

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

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces do.

Front

What is an example of balanced forces?

Back

A book resting on a table.

Front

What does acceleration depend on according to Newton's 2nd law?

Back

Acceleration depends on the net force acting on an object and its mass.
