Newton's First Law

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.

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

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 greater than zero.

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion (net force of zero).

What happens to a hockey puck on a frictionless surface?

Back

A hockey puck on a frictionless surface will continue to slide indefinitely unless acted upon by an unbalanced force.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

If the net force acting on an object is zero, what can be said about its motion?

Back

If the net force is zero, the object will maintain its current state of motion, whether at rest or moving at a constant velocity.

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 state of motion.

Front

What is an example of an unbalanced force?

Back

An example of an unbalanced force is when a person pushes a stationary car, causing it to move.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if it changes its position relative to a reference point over time.
