newtons laws

Front

What is inertia?

Back

Inertia is the tendency of an object to resist a change in its state of motion. It means that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is force?

Back

Force is a push or pull acting upon an object, measured in Newtons (N). It can cause an object to accelerate, decelerate, or change direction.

Front

What does Newton's 2nd law of motion state?

Back

Newton's 2nd 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 Newton's 3rd law of motion?

Back

Newton's 3rd law states that for every action, there is an equal and opposite reaction.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is required to change its motion, according to Newton's 2nd law.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) x acceleration (a).

Front

What is an example of inertia in everyday life?

Back

An example of inertia is when a car suddenly stops, and passengers lurch forward due to their bodies' tendency to continue moving.

Front

What happens to an object in motion if no net force acts on it?

Back

If no net force acts on an object in motion, it will continue to move at a constant velocity.
