Force and Motion

Front

What is force?

Back

A force is a push or pull that can change the motion of an object.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is friction?

Back

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

Front

What is balanced force?

Back

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

Front

What is unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

What happens when a force is applied to an object at rest?

Back

The object will start to move in the direction of the applied force.

Front

How does mass affect motion?

Back

Objects with greater mass require more force to change their motion compared to lighter objects.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion, especially on Earth.
