Newtons Laws

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. For example, a ball at the top of a hill has potential energy because it can roll down.

What does Newton's 2nd Law of Motion state?

Back

Newton's 2nd Law of Motion states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma). This means you need to push or pull harder on heavier objects.

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law of Motion states that for every action, there is an equal and opposite reaction. For example, when air rushes out of a balloon, the balloon moves in the opposite direction.

Front

What is Gravity?

Back

Gravity is a force that pulls objects toward each other. On Earth, it pulls us down towards the ground, allowing us to sit, stand, and walk.

Front

What is Mechanical Force?

Back

Mechanical Force is a force that can cause an object to move or change its motion. For example, writing on paper requires a mechanical force.

Front

What is an example of an object with Kinetic Energy?

Back

An example of an object with Kinetic Energy is a rolling ball. Kinetic Energy is the energy of an object in motion.

Front

What is the relationship between mass and force according to Newton's 2nd Law?

Back

According to Newton's 2nd Law, as the mass of an object increases, the amount of force needed to accelerate it also increases.

Front

What happens to a ball when it is at the top of a hill?

Back

When a ball is at the top of a hill, it has potential energy. If pushed, it will roll down the hill, converting potential energy into kinetic energy.

Front

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

Back

An example of Newton's 3rd Law is when you jump off a small boat; as you push down on the boat, it pushes you up into the air.

Front

What is the effect of gravity on objects?

Back

Gravity pulls objects towards the center of the Earth, which is why things fall when dropped.
