Newton's laws of motion

Front

What is 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

The acceleration of an object depends on the mass of the object and the amount of force applied. It can be expressed with the formula: Force = Mass x Acceleration (F = ma).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What happens to an object's motion when no net force acts on it?

Back

The object will maintain its current state of motion, either at rest or moving at a constant velocity.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

If the mass of an object increases while the force remains constant, the acceleration decreases.

Front

What is inertia?

Back

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

Front

Give an example of Newton's 1st Law of Motion in everyday life.

Back

When a car suddenly stops, passengers lurch forward due to inertia.

Front

What is the relationship between force and acceleration?

Back

Force is directly proportional to acceleration; if the force increases, acceleration increases.

Front

What is an example of Newton's 3rd Law of Motion?

Back

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

Front

What does it mean when we say 'acceleration is directly proportional to force'?

Back

If you double the force applied to an object, its acceleration will also double, assuming mass remains constant.
