Newton's Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

Give an example of Newton's First Law of Motion.

Back

A soccer ball remains motionless until it is kicked by a player.

Front

What happens to the acceleration of an object if you double its mass while applying the same force?

Back

The acceleration will cut in half.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

If a force of 26 N is applied to two balls of different masses, which ball will have the greater acceleration?

Back

The ball with a mass of 0.52 kg will have the greatest acceleration.

Front

What is the standard unit of force?

Back

Newtons (N).

Front

If you have a kilogram of feathers and a kilogram of iron, which requires a greater net force to move?

Back

They require the same net force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the relationship between force, mass, and acceleration?

Back

Force is equal to mass multiplied by acceleration (F=ma).

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero.
