Final Exam Review Physical Science

If you ride your bicycle down a straight road for 500 m then turn around and ride back, your distance is ____________ your displacement.

• less than

• greater than

• equal to

• can't determine

Newton's first law of motion is also called the law of

• inertia

• mass

• force

• velocity

Acceleration is the rate of change of

• position

• time

• velocity

• force

3 m/s north is an example of a (n)

• constant speed

• acceleration

• velocity

• instantaneious speed

A horizontal line on a velocity time graph shows______acceleration

• negative

• positive

• changing

• zero

A single point on a distance-time graph tells the

• instantaneous speed

• average speed

• constant speed

• average velocity

A 300-N force acts on a 25-kg object. The acceleration of the object is

• 12 m/s squared

• 50 m/s squared

• 150 m/s squared

When two balls collide, the momentum of the balls after the collision is explained by

• Newton's 3rd Law

• Newton's second Law

• Newton's 1st Law

• the law of conservation of momentum

In the absence of air, a penny and a feather that are dropped from the same height at the same time will

• fall at the same rate

• fall at different rates

• float

• not have momentum

A real car moving at 10 km/h has ore momentum than a toy car moving at the same speed because the real car

• has greater forward motion

• has less mass

• generates less friction

• has a greater mass
