Newtons Laws Of Motion

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion, resulting in acceleration or a change in direction.

Front

State Newton's 1st 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 2nd Law of Motion?

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

State Newton's 3rd Law of Motion.

Back

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

Front

What is friction?

Back

Friction is a contact force that opposes the relative motion of two surfaces in contact.

Front

What happens when two forces of equal magnitude act in opposite directions?

Back

The object will not move at all, as the forces are balanced.

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

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

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's 2nd Law, the relationship is given by the formula F=ma, where F is force, m is mass, and a is acceleration.

What is an example of an unbalanced force in everyday life?

Back

An example is pushing a shopping cart; if you push harder than the friction opposing it, the cart will accelerate.
