Force and Motion

Front

What is Newton's Second Law of Motion?

Back

It 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 unbalanced force?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it depends on the object's mass.

Front

What does Newton's Third Law of Motion state?

Back

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

Front

What is a force?

Back

A force is a push or pull that is exerted on matter.

Front

What is an example of Newton's Second Law of Motion?

Back

A truck needs a more powerful engine than a small car to accelerate at the same rate.

Front

How does a trampoline demonstrate Newton's Third Law of Motion?

Back

When a boy jumps on a trampoline, he pushes down on the trampoline (action), and the trampoline pushes him up (reaction).

Front

What is the relationship between mass and acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases if the same force is applied.

Front

What is an example of an unbalanced force?

Back

A soccer ball being kicked is an example of an unbalanced force acting on it.

Front

What is the principle behind why a sprinkler spins?

Back

The sprinkler spins due to the principle that every action has an equal and opposite reaction.
