Newton Laws of Motion

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. All objects with mass have inertia.

Front

What does Newton's first law of motion state?

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 the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its state of motion.

Front

What does Newton's second law of motion describe?

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

If two objects collide, what can be said about the forces they exert on each other?

Back

According to Newton's third law, when two objects collide, they exert equal and opposite forces on each other.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.

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.

Front

How does friction affect motion according to Newton's laws?

Back

Friction is a force that opposes motion, and it must be overcome for an object to start moving or to continue moving at a constant speed.

Front

What is the significance of the net force in motion?

Back

The net force is the total force acting on an object, and it determines the object's acceleration and direction of motion.

Front

What happens to an object in motion if no net external force acts on it?

Back

If no net external force acts on an object in motion, it will continue to move at a constant velocity.
