Force and Motion

Front

What is Newton's Second Law?

Back

Newton's Second Law states that the greater the mass of an object, the more force it will take to accelerate the object; the lesser the mass, the less force it will take.

Front

What is a Noncontact Force?

Back

A Noncontact Force is a force that acts at a distance without the objects touching. Examples include gravitational, electric, and magnetic forces.

Front

What is gravity?

Back

Gravity is the attraction or force between you and the Earth.

Front

What is motion?

Back

Motion is a change in location or moving from one place to another.

Front

What unit is used to measure force?

Back

The unit used to measure force is Newton's.

Front

What is a Contact Force?

Back

A Contact Force is a force that acts when two objects are in physical contact with each other.

Front

What is the relationship between mass and acceleration?

Back

The relationship is that greater mass requires more force to achieve the same acceleration.

Front

What is an example of a Noncontact Force?

Back

An example of a Noncontact Force is gravity.

Front

What does it mean to accelerate?

Back

To accelerate means to increase the speed of an object or change its direction.

Front

What is inertia?

Back

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