Exam 1: Physics Force, Acceleration, and Projectile Motion

Projectile will attain its maximum range, if it is fired at an angle of

If initial velocity of an object is zero, then distance covered by it in time t and acceleration of 9.8ms^-2 would be

Gradient of velocity-time graph tells us about object's

Accelerometer detects the

A stone is thrown upwards with initial velocity of 20ms^-1, the height that stone will reach would be

Generators at a power station produce electric power at voltage

If the gradient of a graph is negative, then the acceleration is

Horizontal component of a bouncing ball is

Acceleration of train when it is moving steadily from 4.0ms^-1 to 20ms^-1 in 100s is

As the ball falls towards the ground, its velocity

A train travelling at 20ms^-1 accelerates at 0.5ms^-2 for 30 s, the distance travelled by train is

Only force acting on a bouncing ball is

Gradient of line of velocity-time graph is tells us the

Horizontal distance traveled by a ball if it's thrown with initial velocity of 20ms^-1 at an angle of 30° is

Equation of motion can be used for

If a car starting from rest reaches a velocity of 18ms^-1 after 6.0 s then its acceleration is

An object whose velocity is changing is said to be in a state of

If a spinster staring from rest has acceleration of 5ms^-2 during 1st 2.0s of race then her velocity after 2 s is

If a secondary coil has 40 turns, and, a primary coil with 20 turns is charged with 50 V of potential difference, then the potential difference in the secondary coil would be

Acceleration of free fall depends on the
