Question

What factor explains the tendency of all objects to resist any change in motion?

Question

What type of activity best demonstrates Newton’s third law of motion?

Question

When the brakes are suddenly applied to a moving vehicle, what causes a person to continue to move forward in his seat?

Question

Which of Newton’s Laws states that for every action there is an equal and opposite reaction?

Question

When the driver of a car suddenly makes a sharp turn, why will the passenger slide to the side of the car?

Question

Use Newton’s second law of motion (F=ma) to calculate the acceleration of a 12 kg mass if a force of 45 N acts on it.

Question

Use Newton’s second law of motion (F=ma) to calculate the mass of an object when a force of 28 N accelerates the object 3 m/s/s.

Question

Given the formula, (acceleration = final velocity – starting velocity divided by time), what is the acceleration of the wind if it blows with a velocity of 15 m/s south and five seconds later, the wind’s velocity is 20 m/s south?

Question

Two bicycles ramps have the same height. The first ramp is twice as long as the second ramp. Why does the first ramp have a better mechanical advantage?

Question

What type of simple machine is an inclined plane with one or two slanting sides?

Question

When a machine increases the size of the force exerted, what happens to the distance through which the force is exerted?

Question

To open a bottle, Mary applies a force of 90 N to the bottle opener. The bottle opener applies a force of 225 N to the bottle cap. What is the mechanical advantage of the bottle opener?

Question

A syringe with air is stoppered. It is then pushed in. What can be said of the original air pressure as compared to the final air pressure?

Question

What is the density of a 50 cm3 sample of liquid with a mass of 300 g? (D=m/v)

Question

What is the pressure exerted on the floor by a 5,000 N crate with an area of 10 m2? (Pa=F/a)

Question

What is the weight of a rock with an area of 10m2 that exerts a pressure of 250 Pa in correct SI units? (Pa=F/a)

Question

What would happen if astronauts, who wear pressurized suits in space, took their suits off to go outside of the spaceship?

Question

What causes the napkins to stay on the picnic table even though there is a slight breeze?

Question

What is the force that opposes motion between two surfaces that are touching?

Topic

Describe how mechanical advantages of simple machines reduce the amount of force needed for work.

Topic

Differentiate between kinetic and potential energy. & Describe the affect of force on pressure in a fluid.

Answer

A rocket maneuvering in space, a balloon flying around the room, you sitting in a chair, a rocket launching at Cape Canaveral

Answer

The fluids in their bodies would overcome the pressure outside of their bodies, and they would explode.

Answer

Starting velocity, final velocity, and the total time it takes to change velocity
