The basic difference between instantaneous and average speed is that

Does any change in the motion of an object, mean acceleration has occurred?

A measure of how fast your speed is changing as you travel to campus is a measure of

A bicyclist pedals at a speed of 5.0 km/h. How far does he travel in 80 minutes?

A team exerts a force of 10 N towards the south in a tug of war. The other, opposite team, exerts a force of 17 N towards the north. The net force is

You are moving a grocery cart at a constant speed in a straight line down the aisle of a store. For this situation the forces on the cart are

You are outside a store, moving a loaded grocery cart down the street on a very steep hill. It is difficult, but you are able to pull back on the handle and keep the cart moving down the street in a straight line and at a constant speed. For this situation the forces on the cart are

Neglecting air resistance, a ball in freefall near the earth's surface will have

Neglecting air resistance, an object is observed to fall how far in 3.0s?

From a bridge, a ball is thrown straight up at the same time a ball is thrown straight down with the same initial speed. Neglecting air resistance, which ball would have a greater speed when it hits the ground?

A gun is aimed horizontally at the center of an apple hanging from a tree. The instant the gun is fired the apple falls and the bullet

If an astronaut has a weight of 450 N on the earth, what would be her weight on the moon?

According to the third law of motion, which of the following must be true about a car pulling a trailer?

A small sports car and a large SUV collide head on and stick together without sliding. Which vehicle had the larger momentum change?

Again consider the small sports car and large SUV that collided head on and stuck together without sliding. Which vehicle must have experienced the larger deceleration during the collision?

Considering the gravitational attraction between the earth and moon, the

A straight line distance covered during a certain amount of time describes an object's

How fast an object is moving in a particular direction is described by

Acceleration occurs when an object undergoes

For motion to occur, what must happen?

Motion can be changed in how many different ways?

A car moving at 60 mi/hr comes to a stop in 10 s when the driver slams on the brakes. In this situation, what does 60 mi/hr represent?

A car moving at 60 mi/hr comes to a stop in 10 s when the driver slams on the brakes. In this situation, what is the final speed?

Galileo argued against Aristotle's idea that

According to Galileo, an object moving without opposing friction or other opposing forces will

In free fall, an object is seen to have a (an)

Is it possible to throw a football with a flat trajectory?

A tennis ball is hit, moving upward from the racket at some angle to the horizon before it curves back to the surface in the path of a parabola. While moving along this path

A push or a pull that is capable of changing the state of motion of an object is a (an)

Newton's first law of motion describes

You are standing freely on a motionless shuttle bus.When the shuttle bus quickly begins to move forward, you

Mass is measured in kilograms, which is a measure of

Newton's third law of motion states that forces occur in matched pairs that act in opposite directions between two different bodies. This happens

Suppose the mass of a moving scooter is doubled and its velocity is also doubled. The resulting momentum is

Two identical moons are moving in identical circularpaths, but one moon is moving twice as fast as the otheris. Compared to the slower moon, the centripetal force required to keep the faster moon on the path is
