Forces, Motion, Energy, and Waves

Front

What is Newton's 1st Law of Motion?

Back

Objects resist changes in motion unless acted on by an unbalanced force. Example: A soccer ball stays still until kicked.

Front

What is Newton's 2nd Law of Motion?

Back

More force = more acceleration; more mass = less acceleration. Example: Pushing a shopping cart vs. pushing a car.

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there's an equal and opposite reaction. Example: Jumping off a canoe pushes the canoe back.

Front

What is the formula for speed?

Back

Speed = Distance ÷ Time. Measured in m/s, km/h, etc.

Front

What does a straight upward slope on a distance-time graph indicate?

Back

Constant speed.

Front

What is Kinetic Energy?

Back

Energy of motion. Example: A running dog, a moving car.

Front

What is Potential Energy?

Back

Stored energy. Gravitational: depends on height and mass. Example: apple on a tree.

Front

What type of energy is stored in a stretched bow before releasing an arrow?

Back

Elastic energy.

Front

What are the three methods of heat transfer?

Back

Conduction, Convection, Radiation.

Front

What type of heat transfer occurs when you warm your hands near a fire without touching it?

Back

Radiation.
