Newton's first law of motion

Front

What is Newton's first law of motion?

Back

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 a net external force.

Front

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.

Front

How does mass affect inertia?

Back

Objects with greater mass have greater inertia, meaning they are harder to start or stop moving.

Front

What direction does friction act in relation to movement?

Back

Friction acts in the opposite direction of movement.

Front

What happens to a moving object when balanced forces act on it?

Back

The object will continue to move at a constant speed and in the same direction.

Front

What is an example of an object in motion that demonstrates Newton's first law?

Back

A hockey puck sliding on ice will continue to slide until friction or another force stops it.

Front

What is the relationship between force and motion according to Newton's first law?

Back

A net external force is required to change the motion of an object.

Front

What is an example of inertia in everyday life?

Back

When a car suddenly stops, passengers lurch forward due to inertia.

Front

What is the effect of unbalanced forces on a moving object?

Back

Unbalanced forces will cause the object to accelerate, decelerate, or change direction.

Front

How does friction affect motion?

Back

Friction opposes motion, causing objects to slow down or stop.
