EOCA Physical Science A

The ability to do work

• Power

• Energy

• Force

• Joule

ON object raised above the ground has

• Potential energy

• heat energy

• chemical energy

• nuclear energy

A boat motor changes chemical energy into

• light energy

• Mechanical energy

• nuclear energy

• electricity

Work is measured in units called

• Joules

• Power

• Force

• Newtons

The amount of work done per unit of time is called

• Energy

• Force

• Power

• Watt

What is a PUSH or PULL of an object?

• Motion
• Force
• Friction
• Gravity

Why is it harder for the boy in Image B to get down the hill?

• Motion
• Friction
• Work
• Displacement

Which force produces a change in motion?

• unbalanced force
• balanced force
• gravitational force
• frictional force

If these boys are pulling with the same amount of force.  What will happen?

• The boy in blue will win.
• They will not move at all.
• The boy in red will win.
• Both will fall down.

When you tell the direction and speed of an object, you give its

• motion
• velocity
• acceleration
• mass
