Newtons first law

Front

What is Newton's First Law?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Front

What type of forces cause a change in an object's motion?

Back

Unbalanced forces.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of an object, making it harder to move.

Front

A change in an object's position is called ______.

Back

Motion.

Front

If an object is moving at a set speed and in a set direction, it will remain at that same ____

Back

Velocity.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the relationship between force and motion?

Back

A net force acting on an object causes it to accelerate in the direction of the force.

Front

What is an example of balanced forces?

Back

Two people pushing a car in opposite directions with equal force.

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.
