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 with the same speed and in the same direction unless acted upon by an unbalanced 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. (F = ma)

Front

What is Newton's Third Law of Motion?

Back

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

Front

How do you calculate acceleration?

Back

Acceleration (a) is calculated by the formula: a = F/m, where F is the net force and m is the mass.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surfaces in contact.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

What happens to an object when the net force acting on it is zero?

Back

If the net force is zero, the object will maintain its current state of motion, either at rest or moving at a constant velocity.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating force?

Back

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