Newtons Laws 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 with the same speed and in the same direction unless acted upon by an unbalanced 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. (F = ma)

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is inertia?

Back

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

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces are not equal and can cause an object to accelerate, decelerate, or change direction.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g).

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, such as the Earth and an object.

Front

What is the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with a surface.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object in contact with a surface.
