Force & Motion

How can you determine the speed of a moving train?

• Multiply the distance traveled by the time spent moving

• Add the distance traveled to the time spent moving

• Divide the distance traveled by the time spent moving

• Subtract the time spent moving from the distance traveled

Objects in motion tend to stay in motion because of the property of:

• Gravity

• Friction

• Inertia

• Magnetism

Sue is the pitcher for her community softball team. What force causes the baseball to change direction when it is hit by the bat?

• Gravity

• The batter's force on the ball with the bat

• The pitcher's throw

• Wind resistance

The distance traveled in an amount of time is called:

• Velocity

• Acceleration

• Force

• Speed

______________________ describes when a moving object speeds up.

• Deceleration

• Acceleration

• Velocity

• Inertia

A _________ is a push or pull.

What is the force of attraction to a magnet?

• Gravity

• Friction

• Magnetism

• Electricity

What is a force that resists motion?

• Acceleration

• Friction

What pulls a force of attraction down towards the center of the Earth?

• Magnetism

• Friction

• Gravity

• Wind

Do rough surfaces cause more or less friction?

• More friction

• Less friction

• No friction

• Friction doesn't depend on surface roughness
