Newton's Laws

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion, either by speeding up, slowing down, or changing direction.

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, making it harder for the object to move.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law 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 states that the acceleration of an object depends on the mass of the object and the amount of force applied, expressed as F=ma (Force = mass x acceleration).

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.

What happens to a ball kicked in space?

Back

The ball continues to move in the same direction unless it hits something or is affected by gravity or another force.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion, especially when they are in free fall.

Front

How does mass affect motion?

Back

The greater the mass of an object, the more force is required to change its motion.

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it is directly related to the mass of the object.
