What is the velocity of an object at its highest point when tossed vertically upward?

Back

0 m/s

Front

What is the relationship between acceleration and velocity in projectile motion?

Back

Acceleration is directed downward (toward the Earth) while velocity can be upward or downward depending on the object's position in its trajectory.

Front

What does a broken scale reading different values on Earth and another planet measure?

Back

Weight, as it varies with gravitational force.

Front

What are the SI units for force?

Back

Newtons (N)

Front

Back

Horizontal displacement.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.8 m/s².

Front

How does the velocity of a projectile change during its flight?

Back

It decreases as it rises, becomes zero at the highest point, and increases as it falls.

Front

What is the formula for calculating the range of a projectile?

Back

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object (constant), while weight is the force exerted by gravity on that mass (varies with gravity).

Front

What is the trajectory of a projectile?

Back

A parabolic path due to the influence of gravity.
