Force and Motion Classwork

Front

What is a force?

Back

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

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

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

Front

What is friction?

Back

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

Front

How does friction affect motion on different surfaces?

Back

Friction is greater on rough surfaces, making objects move slower compared to smooth surfaces.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the pull of the Earth on objects.

Front

What happens to an object when a force is applied?

Back

When a force is applied, it can change the object's speed, direction, or shape.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, making it harder to change its motion.

Front

What is motion?

Back

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