A-level PE Projectile Motion

What is Projectile Motion?

• The speed at which an object or human travels through the air

• Distance coved by an object or human once in the air

• Movement of an object or human as they travel through the air

• The angle of which a ball travels through the air

Which of these factors does not affect horizontal displacement?

• Direction of release

• Angle of release

• Height of release

• Speed of release

The optimum angle of release is dependent upon the release height and object mass. True or False

• True

• False

What is the optimal angle of release for a long jump?

• Less than 45 degrees

• 45 degrees

• More then 45 degrees

What is the result of a greater release height?

• Increase in horizontal displacement and distance

• Increase in horizontal displacement and therefore a decrease in distance

• Decrease in distance and horizontal displacement

• Decrease angle of release

Having a lower release velocity of a projectile, will have what effect on the horizontal displacement?

• Remain the same

• Increase

• Decrease

What is a parabola?

• Movement of an object

• The tracked movement of a human through the air

• A graph that represents the velocity of an object or human

• A uniform curve that is symmetrical at its highest point

What are the two factors that affect whether a parabola is a true parabola or a distorted parabola?

• Weight and Speed

• Air resistance and Weight

• Velocity and Air resistance

• Angle of release and Air Resistance

What force acts on an object to increase its negative vertical component before landing?

• Air resistance

• Velocity

• Force generated by the athlete

• Gravity

By adding both the vertical vector and horizontal vector, you are able to find the ................ vector
