Force & Motion

When held at shoulder height the forces acting on the basketball are:

• Balanced
• Unbalanced
• Stronger in one direction
• Weak

If you let go of the basketball it will fall towards the ground because the forces acting on it are:

• Unbalanced
• Balanced
• Equal in size, but opposite in direction
• Weak

The volleyball is being pulled towards the ground by which force?

• Friction
• Gravity
• Driving Force
• Kinetic Energy

As a skateboarder rolls down a ramp, what force causes him to slow down and eventually stop?

• Gravity
• Friction
• Potential Energy
• Heat

According to Newton's first law, the law of inertia, a bike in motion will...

• Remain at rest unless acted on by a balanced force
• Remain in motion unless acted on by an unbalanced force
• slow down even if no forces act on it

According to Newton's first law, the law of inertia, a bike at rest will...

• Speed up until a balanced force acts on it.
• Remain in motion unless acted on by an unbalanced force.
• Remain at rest unless acted on by an unbalanced force.

According to Newton's second law, the law of acceleration, it takes more force to accelerate a bowling ball than a soccer ball since a bowling ball has:

• Less Mass
• More Mass
• More Inertia
• Less Inertia

According to Newton's second law, the law of acceleration, if you push on a lego house and a real house with the same amount of force:

• The real house will be pushed further because it has more mass.
• The lego house will be pushed further because it has less mass.
• The lego house will be pushed further because it has more mass.
• Both houses will be pushed the same distance because mass does not effect motion.

Motion is

• The action or process of moving or being moved.
• Anything that occupies space and has mass; made up of atoms
• A push or a pull
• The tendency of matter to resist change in motion.

Inertia is

• The action or process of moving or being moved.
• Anything that occupies space and has mass; made up of atoms
• A push or a pull
• The tendency of matter to resist change in motion.
