Forces and motion

Forces that cause a change in motion.

• Balanced Forces

• Unbalanced Froces

• Force

• Gravity

A force of attraction between two objects.

• Balanced Force

• Unbalanced Force

• Friction

• Gravity

The speed of an object in a particular direction.

• Velocity

• Speed

• Acceleration

• Force

When free fall happens, what is the only force acting on the object?

• Inertia

• Gravity

• Drag

• Wind

• Force

What is the tendency of all objects to resist a change in motion unless acted on by an outside force?

• Gravity

• Inertia

• Net Force

• Friction

This energy is due to an object's position above the ground.

• Chemical Energy

• Mechanical Energy

• Gravitational Potential Energy

• Kinetic Energy

Which is not a type of friction?

• sliding

• fluid

• rolling

• static

• regular

Centripetal force is

• a force that affects an object

• a type of non-motion

• a force that makes an object move in a squarish path

• it makes it move in a circular path

• it does not affect how an object moves

Acceleration due to gravity on Earth is always

• 0.98 m/s²

• 9.8 m/s²

• 98 m/s²

• 7.9 m/s²
