Force and Motion

Front

What is Force?

Back

Force is any push or pull on an object.

Front

What is Acceleration?

Back

Acceleration is any change in the speed or direction of an object.

Front

What is Speed?

Back

Speed is the distance something travels in a set amount of time.

Front

What happens if an unbalanced force acts on a stationary object?

Back

The object will accelerate in the direction of the force.

Front

What force keeps satellites in orbit around Earth?

Back

Gravity.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

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

Front

What is inertia?

Back

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

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 an unbalanced force.

Front

What is the relationship between mass and force?

Back

According to Newton's Second Law, Force = Mass x Acceleration.
