Newton's Laws

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by an unbalanced force.

Front

Define balanced forces.

Back

Balanced forces are two or more forces acting on an object that cancel each other out, resulting in no change in motion.

Front

What is an example of balanced forces?

Back

A textbook resting on a table is an example of balanced forces.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

Calculate the acceleration of a 10 kg box when a force of 50 N is applied.

Back

5 m/s² (using F=ma, where F=50N and m=10kg).

Front

What is the net force?

Back

The net force is the total force acting on an object after all the forces are combined.

Front

What does Newton's Third Law of Motion state?

Back

For every action, there is an equal and opposite reaction.

Front

Give an example of Newton's Third Law of Motion.

Back

When Zoe steps out of a canoe, the canoe moves backward as a reaction to her stepping forward.

Front

What is inertia?

Back

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

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, change direction, or change shape.
