Newton's Laws Test Review Flashcardizz

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. This can be expressed with the formula: F = ma (Force = mass x acceleration).

Front

If the net force on an object is doubled, what happens to its acceleration?

Back

If the net force is doubled while the mass remains constant, the acceleration also doubles.

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

Mass and acceleration are inversely related; as mass increases, acceleration decreases if the net force remains constant.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction to the movement.

Front

What happens to the forces during a collision between two objects?

Back

According to Newton's Third Law, during a collision, the forces exerted by the two objects on each other are equal in magnitude and opposite in direction.

Front

How do you calculate acceleration?

Back

Acceleration can be calculated using the formula: a = F/m (acceleration = net force / mass).

Front

What is the effect of increasing mass on acceleration if the force is constant?

Back

If the mass increases while the force remains constant, the acceleration decreases.

Front

What is the significance of the net force acting on an object?

Back

The net force is the total force acting on an object, determining its acceleration according to Newton's Second Law.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is the formula for calculating net force?

Back

Net force can be calculated using the formula: F_net = F_applied - F_friction (Net force = applied force - frictional force).
