What is Newton's Third Law of Motion?

Back

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

Front

What happens to the weight of an object if the gravitational acceleration doubles?

Back

The weight of the object also doubles.

Front

How do you calculate force using mass and acceleration?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

If a car has a mass of 1000 kg and accelerates at 2 m/s², what is the force applied?

Back

2000 N.

Front

What unit is used to measure force?

Back

Newton (N).

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravitational acceleration.

Front

What is gravitational acceleration on Earth?

Back

Approximately 9.8 m/s².

Front

If a person pushes a wall with a force of 50 N, what force does the wall exert back?

Back

50 N.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g).

Front

What does it mean when we say force is a vector quantity?

Back

It means force has both magnitude and direction.
