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 motion. It can cause an object to start moving, stop moving, or change direction.

Front

What does Newton's 1st Law of Motion state?

Back

Newton's 1st Law of Motion states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant speed and in a straight line unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law of Motion states that the acceleration of an object depends on the mass of the object and the amount of force applied. It can be expressed with the formula F=ma (Force = mass x acceleration).

Front

What does Newton's 3rd Law of Motion state?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The more mass an object has, the more inertia it has.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion. Unbalanced forces are not equal, causing a change in motion.

Front

What is gravitational force?

Back

Gravitational force is the force of attraction between two objects due to their mass. It pulls objects toward each other.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

According to Newton's 2nd Law, as the mass of an object increases, the acceleration decreases if the same amount of force is applied.

Front

What happens when you jump?

Back

When you jump, you exert a force on the ground, pushing it down. According to Newton's 3rd Law, the ground exerts an equal and opposite force that pushes you upward.

Front

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

Back

An example of Newton's 1st Law is when a passenger in a car continues to move forward when the car suddenly stops.
