Force and Motion Review

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass. It is the reason why objects fall towards the Earth.

Front

What is motion?

Back

Motion is the change in position of an object over time. It can be described in terms of speed, direction, and acceleration.

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time, while velocity is speed with a direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

What is Newton's First Law of Motion?

Back

Newton's First 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 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 (F=ma).

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

What is balanced force?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What is unbalanced force?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in the motion of an object.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.
