Newton's First and Second Law

Front

What is Newton's First Law of Motion?

Back

An object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is inertia?

Back

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

Front

What role does friction play in motion?

Back

Friction is a force that opposes the motion of an object, causing it to slow down or stop.

Front

What is a balanced force?

Back

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

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and opposite, causing a change in the motion of an object.

Front

How do balanced forces affect a moving object?

Back

Balanced forces acting on a moving object will cause it to continue moving at a constant speed and in the same direction.

Front

What happens to an object in motion when an unbalanced force acts on it?

Back

An unbalanced force will cause the object to accelerate, decelerate, or change direction.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it is harder to change its state of motion.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can be a change in speed or direction.
