FORCE AND MOTION

Front

What is force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What is motion?

Back

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

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.

Front

What is an unbalanced force?

Back

An unbalanced force is when two forces acting on an object are not equal in size and opposite in direction, causing the object to accelerate.

Front

What is a balanced force?

Back

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

Front

How does mass affect gravitational force?

Back

More mass means more gravitational force; the greater the mass of an object, the stronger the gravitational pull it experiences.

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 an unbalanced force.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity; it can be a change in speed or direction.

Front

What is friction?

Back

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