PS Unit 7 Forces

Front

With unbalanced forces, the object will move in the direction of the _______ force.

Back

larger

Front

A measure of how much matter an object has is--

Back

mass

Front

An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. This is known as:

Back

Newton's First Law of Motion

Front

If you increase the mass on an object, its acceleration:

Back

decreases

Front

When a cannon fires a cannonball, which force is the reaction force?

Back

The cannon moving backward

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma)

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

What does Newton's Second Law of Motion state?

Back

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

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass (Weight = Mass x Gravity).
