Forces and Motion TEKS 5.6

Front

What is a 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 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 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 gravity?

Back

Gravity is the force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

How does surface texture affect motion?

Back

Rough surfaces create more friction, requiring more force to move an object compared to smooth surfaces.

Front

What is a spring scale?

Back

A spring scale is a tool used to measure the force applied to an object, typically in units of newtons.

Front

What happens when you pull an object with a constant force?

Back

If you pull an object with a constant force, it will accelerate at a steady rate.

Front

What is the effect of increasing mass on force needed to move an object?

Back

Increasing the mass of an object increases the force needed to move it.
