Forces and Motion

Front

What is a balanced force?

Back

A balanced force is when there is no net force acting on an object, meaning the forces are equal in size and opposite in direction.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the net force acting on an object is not zero, causing the object to accelerate in the direction of the greater force.

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 an unbalanced force.

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 is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd 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).

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Front

What is the direction of friction?

Back

Friction acts in the opposite direction to the motion of the object.

Front

What is net force?

Back

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

What is an example of a balanced force?

Back

An example of a balanced force is a book resting on a table, where the force of gravity pulling it down is balanced by the normal force of the table pushing it up.
