1.3 Newton's Laws & Calculating Force

In science, a ________ is simply a push or a pull.

• distance
• force
• inertia
• object

All forces have BOTH

• position and balance
• size and direction
• direction and position
• motion and size

A force can cause an object to change its _____ or _______.

• speed or net force
• direction or net force
• speed or direction

The combination of all the forces acting on an object is ____________.

• net force
• the total distance traveled
• force
• F = ma

When forces act in the same direction, you simply ______ them.

• subtract
• divide
• multiply
• add

When forces act in opposite directions, you ______ the smaller force from the larger force to determine the net force.

• subtract
• divide
• multiply
• add

If the net force on an object is NOT 0 N, the forces are ___________. This will produce a change in the object's motion.

• acceleration
• balanced
• net force
• unbalanced

Newton's first law is also called the law of _____.

• 1st
• speed
• direction
• inertia

An object at rest stays at rest, and an object in motion stays in motion at the same speed and direction, unless it experiences an unbalanced force. Which law is this?

• first law
• second law
• third law
• no law

The acceleration of an object depends on the mass of the object and the amount of force applied.

• first law
• second law
• third law
• no law
