What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in a net force of zero. This means the object will not accelerate.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What happens when an object is slowing down in terms of forces?

Back

When an object is slowing down, the forces acting on it are unbalanced, meaning there is a nonzero net force acting in the opposite direction of the motion.

Front

What is the relationship between net force and acceleration?

Back

According to Newton's second law, the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as the mass of the object multiplied by the acceleration due to gravity (W = mg).

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.8 m/s².

Front

If a 10 kg object is on Earth, what is its weight?

Back

The weight of a 10 kg object on Earth is 98 N (using W = mg, where g = 9.8 m/s²).

Front

What is Newton's first law of motion?

Back

Newton's first law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's second law of motion?

Back

Newton's second law 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 Newton's third law of motion?

Back

Newton's third law states that for every action, there is an equal and opposite reaction.
