Forces and Motion

Front

What does a graph showing a straight line indicate about an object's motion?

Back

Constant Speed

Front

What is the force that opposes motion between any surfaces that are touching?

Back

Friction

Front

What is the tendency of an object to resist a change in its motion?

Back

Inertia

Front

If a kilogram of feathers and a kilogram of iron are both at rest, which requires a greater net force to move?

Back

Same

Front

What is the formula to find force?

Back

Force = mass x acceleration

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is velocity?

Back

The speed of an object in a specific direction.

Front

What is the difference between speed and velocity?

Back

Speed is scalar (magnitude only), while velocity is vector (magnitude and direction).

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's Second 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.
