Front

Who formulated the Law of Universal Gravitation?

Back

Sir Isaac Newton

Front

What is the effect of force on the direction of a moving object?

Back

The force can change the direction of the object.

Front

What is the force that attracts objects toward the center of the Earth?

Back

Gravity

Front

What is the term for the force that opposes the motion of two surfaces sliding past each other?

Back

Friction

Front

What is defined as a change in an object's position over time?

Back

Motion

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force increases with mass.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = ma)

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 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.
