Newton's First Law of Motion

Front

What is Newton's First Law of Motion?

Back

Newton's First Law of Motion states that an object at rest will remain at rest, and an object in motion will continue in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

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 greater its inertia.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause a change in the motion of an object. They result in a net force that is not zero.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

How does gravity affect motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion by accelerating them downward.

Front

What role does friction play in motion?

Back

Friction is a force that opposes the motion of an object, causing it to slow down or stop.

Front

Why do objects in motion stay in motion?

Back

Objects in motion stay in motion due to inertia, which is the resistance to change in their state of motion.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its motion.

Front

Can an object be in motion if no forces are acting on it?

Back

Yes, an object can be in motion if no unbalanced forces are acting on it, as it will continue moving at a constant velocity.

Front

What happens to a moving object when a frictional force acts on it?

Back

When a frictional force acts on a moving object, it will slow down and eventually come to a stop.
