Newton Laws

Front

What is Newton's 1st 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 an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is net force?

Back

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

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

How do you determine the direction of motion when forces are unbalanced?

Back

The object will move in the direction of the larger force.

Front

If a truck is moving and suddenly stops, what happens to the objects inside?

Back

The objects will continue moving forward due to inertia, as described by Newton's 1st Law.

Front

What is inertia?

Back

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

Front

If a net force of 4 N to the left is acting on an object, what can be said about the forces acting on it?

Back

The forces are unbalanced, and the object will accelerate to the left.
