Newton's Laws Review

Front

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 on an object.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is a Newton?

Back

A Newton (N) is the SI unit of force, defined as the amount of force required to accelerate a one-kilogram mass by one meter per second squared.

Front

How do you calculate distance traveled?

Back

Distance traveled can be calculated using the formula: Distance = Speed × Time.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, resulting in a net force that causes an object to accelerate.

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 relationship between mass and acceleration in Newton's 2nd Law?

Back

According to Newton's 2nd Law, 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 terminal velocity?

Back

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.

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.
