Understand Inertia and Forces in Motion

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It means that an object at rest will stay at rest, and an object in motion will continue moving at a constant velocity unless acted upon by an unbalanced force.

Front

What does Newton's First Law state?

Back

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

Front

What is a force?

Back

A force is a push or pull that acts on an object, causing it to change its velocity.

Front

How does mass affect inertia?

Back

The inertia of an object depends on its mass; the greater the mass, the greater the inertia, meaning it is harder to change its state of motion.

Front

What happens to an object in motion if no net forces act on it?

Back

An object in motion will continue in constant motion in a straight line if no net forces act on it.

Front

What is an unbalanced force?

Back

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

Front

What is the relationship between force and motion?

Back

Force is required to change the motion of an object. If the net force acting on an object is zero, its motion remains unchanged.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surfaces in contact.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object; it will either remain at rest or continue moving at a constant velocity.
