Motion

Front

What is inertia?

Back

Inertia is the tendency of an object to remain at rest or in motion unless acted upon by an external 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 unless acted upon by an unbalanced force.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to move in the direction of the greater force.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object does not move.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is gravitational force?

Back

Gravitational force is the force that pulls objects toward each other, such as the force that pulls us toward the Earth.

Front

What is the effect of a larger mass on inertia?

Back

A larger mass has more inertia, meaning it requires more force to change its motion.

Front

What is the relationship between force and motion?

Back

A force applied to an object can change its speed or direction of motion.

Front

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

Back

A seatbelt in a car keeps you in place when the car suddenly stops, demonstrating inertia.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.
