Newton's Laws

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is the definition of mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

How does mass affect the force required to move an object?

Back

A greater mass requires a greater applied force to achieve the same acceleration, according to Newton's Second Law (F=ma).

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward the center of the Earth, affecting their motion, especially when they are in free fall.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, such as an object at the top of a hill.

Front

Where is kinetic energy highest in a roller coaster?

Back

Kinetic energy is highest at the lowest point of the roller coaster, where the speed of the coaster is greatest.

Front

What is friction?

Back

Friction is a force that opposes the relative motion of two surfaces in contact, causing an object to slow down.

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it is directly related to the mass of the object.

Front

What happens to a ball thrown into the air when it reaches its highest point?

Back

At its highest point, the ball's velocity is zero before it begins to fall back down due to gravity.
