Applying Newton's Laws of Motion

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion, resulting in acceleration or a change in direction.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

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 (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Front

What is a balanced force?

Back

A balanced force is a force that does not cause a change in motion because the forces acting on an object are equal in size and opposite in direction.

Front

What happens during a collision between two objects?

Back

During a collision, two objects exert equal and opposite forces on each other, resulting in a change in their motion.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

According to Newton's 2nd Law, as mass increases, acceleration decreases for a given force.

Front

What is an example of Newton's 1st Law in everyday life?

Back

A seatbelt in a car prevents passengers from continuing to move forward when the car suddenly stops.

Front

What is an example of Newton's 3rd Law in action?

Back

When you jump off a small boat, you push the boat backward as you move forward.
