Newton's Laws of Motion - Make-up #2

What is the first law of motion?

• The first law of motion is the law of gravity.

• The first law of motion is the law of momentum.

• The first law of motion is the law of inertia.

• The first law of motion is the law of acceleration.

What is inertia?

• The ability of an object to change its motion easily.

• The force that causes an object to move.

• Resistance of an object to changes in its motion or rest.

• The speed at which an object moves.

According to Newton's first law of motion, an object at rest will stay at rest unless acted upon by what?

• inertia

• friction

• external force

• gravity

What is the tendency of an object to resist changes in its motion?

• momentum

• acceleration

• friction

• inertia

What is the mass of an object with a weight of 50 N and an acceleration due to gravity of 9.8 m/s^2?

• 50 kg

• 98 kg

• 5.1 kg

• 0.5 kg

What is the relationship between mass and inertia?

• Mass has no effect on inertia.

• Inertia is directly proportional to velocity.

• Mass and inertia are directly proportional.

• Mass and inertia are inversely proportional.

What is the relationship between mass and acceleration?

• Acceleration is inversely proportional to force and directly proportional to weight

• Acceleration is directly proportional to mass and force

• Acceleration is directly proportional to force and inversely proportional to mass.

• Mass and acceleration are unrelated

What is the formula to calculate force?

• force = mass x acceleration

• force = mass - acceleration

• force = mass + acceleration

• force = mass / acceleration

What is the formula to calculate acceleration?

• acceleration = final velocity + initial velocity * time

• acceleration = (final velocity - initial velocity) / time

• acceleration = final velocity / initial velocity * time

• acceleration = final velocity * initial velocity / time
