Newton's Laws

Front

What does 'Forces come in pairs' represent?

Back

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

Front

What is the tendency of an object to resist a change in motion?

Back

Inertia is the property of matter that causes it to resist changes in its state of motion.

Front

What is the Law of Inertia?

Back

Newton's 1st law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by a net external force.

Front

How do you calculate mass using net force and acceleration?

Back

Mass (m) can be calculated using the formula: m = F/a, where F is the net force and a is the acceleration.

Front

What is the relationship between mass and inertia?

Back

Objects with greater mass have greater inertia, meaning they resist changes in motion more than lighter objects.

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

What is an example of Newton's 3rd law in everyday life?

Back

When you jump off a small boat, you push the boat backward as you move forward.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula: F = m * a, where m is mass and a is acceleration.

Front

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

Back

An object in motion will continue to move at a constant velocity if no net force acts on it, according to Newton's 1st law.

Front

What is the significance of the net force in Newton's 2nd law?

Back

The net force is the total force acting on an object, and it determines the object's acceleration.
