Newton's Laws

Front

What are Newton's Three Laws of Motion?

Back

1. Newton's 1st Law: An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force. 2. Newton's 2nd Law: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma). 3. Newton's 3rd Law: For every action, there is an equal and opposite reaction.

Define speed in terms of distance and time.

Back

Speed is the distance traveled per unit of time. It can be calculated using the formula: Speed = Distance / Time.

What does Newton's 1st Law of Motion state?

Back

Newton's 1st Law states that an object at rest will remain at rest, and an object in motion will continue moving at a constant velocity unless acted upon by a net external force.

Front

Explain Newton's 2nd Law of Motion with an example.

Back

Newton's 2nd Law states that the acceleration of an object depends on the mass of the object and the amount of force applied. For example, pushing a car (large mass) requires more force to accelerate than pushing a bicycle (small mass).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

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

Back

According to Newton's 2nd Law, as mass increases, acceleration decreases for a given force. This means that heavier objects require more force to achieve the same acceleration as lighter objects.

Front

What is the relationship between action and reaction forces?

Back

According to Newton's 3rd Law, for every action force, there is an equal and opposite reaction force. This means that forces always occur in pairs.

Front

Provide an example of Newton's 3rd Law in everyday life.

Back

When you jump off a small boat onto a dock, you push the boat backward as you move forward. This is an example of action and reaction forces.

Front

What is a position-time graph?

Back

A position-time graph shows the position of an object at different times. A straight line indicates constant velocity, while a curved line indicates acceleration.

Front

What does a horizontal line on a position-time graph represent?

Back

A horizontal line on a position-time graph represents an object at rest, as its position does not change over time.
