Force and Motion

Front

What is the force that pulls objects toward the center of the Earth?

Back

Gravity is the force that pulls objects toward the center of the Earth.

Front

What is the tendency of an object at rest to stay at rest unless acted upon by a force?

Back

Inertia is the tendency of an object at rest to stay at rest unless acted upon by a force.

Front

What slows down the motion of an object or keeps it from starting?

Back

Friction slows down the motion of an object or keeps it from starting.

Front

If a tennis ball, a baseball, and a golf ball are dropped together from a high place, which ball will land first?

Back

They land at the same time.

Front

An object with a lot of mass needs more force or less force to be moved?

Back

An object with a lot of mass needs more force to be moved.

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.

Front

What is inertia?

Back

Inertia is the property of matter that causes it to resist changes in its state of motion.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is needed to change its motion.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of objects moving through the air.
