Unit 4 Force and Motion

Front

What force causes a baseball to accelerate downward after being thrown?

Back

Gravitational force.

Front

What is the term for a change in an object's position compared to objects around it?

Back

Motion.

Front

If a bird flies at 12.5 m/s and the wind speed is 4.5 m/s, what is the speed of the bird when it flies with the wind?

Back

17 m/s.

Front

How do you calculate the net force when two forces are acting in opposite directions?

Back

Add the magnitudes of the forces and indicate the direction of the larger force.

Front

What is the formula for average speed?

Back

s = d / t.

Front

What is the effect of gravitational force on objects in motion?

Back

It causes objects to accelerate downward towards the Earth.

Front

Define force in the context of motion.

Back

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

Front

What is the relationship between speed and distance traveled over time?

Back

Speed is the distance traveled divided by the time taken.

Front

What happens to the motion of an object when a net force is applied?

Back

The object will accelerate in the direction of the net force.

Front

What is air resistance and how does it affect motion?

Back

Air resistance is a force that opposes the motion of an object through air, slowing it down.
